    ABSTRACT: The B-doped ZrO2 (B-ZrO2) samples with different B/Zr ratios were synthesized using zirconium oxychloride and boric acid as the precursors. Their crystallographic phase retained as tetragonal ZrO2 after the doping of B; however, the amount of the Lewis acid sites increased from 46.1 μmolNH3 g−1 on ZrO2 to 100.6 μmolNH3 g−1 on B-ZrO2(1/10) with the nominal B/Zr molar ratio of 1/10. The Ru/B-ZrO2 catalysts were then prepared by chemical reduction, and their electronic and structural properties were systematically characterized by spectroscopic techniques. It is identified that the Ru nanoparticles (NPs) supported on these B-ZrO2 samples exhibited similar size, chemical state, and microstructure. In the partial hydrogenation of benzene, the turnover frequency of benzene was linearly proportional to the amount of the acid sites on the supports, whereas the selectivity toward cyclohexene displayed a volcanic evolution passing through a maximum of 88% on the Ru/B-ZrO2(1/15) catalyst. Kinetic analysis indicated that the acid sites improved the rate constants of the benzene to cyclohexene step (k1) and the cyclohexene to cyclohexane step (k2) to different degrees. The resulting k1/k2 ratio increased from 3.7 × 10−2 l mol−1 (Ru/ZrO2) to 4.8 × 10−2 l mol−1 (Ru/B-ZrO2(1/15)), and then declined to 4.1 × 10−2 l mol−1 (Ru/B-ZrO2(1/10)), which explained the volcanic evolution of the selectivity toward cyclohexene with respect to the acid amount.

    ABSTRACT: Disk- and rod-shaped hexagonal ZnO crystals with various length-to-diameter aspect ratios were controllably synthesized via a facile solution route by adjusting the precursor concentration. The shape and the dimension of the synthesized ZnO crystals were observed by scanning electron microscopy (SEM). The wurtzite structure and the growth habit were determined by powder X-ray diffraction (XRD) and transmission electron microscopy (TEM) coupled with selected-area electron diffraction (SAED). It is found that with the lowering of the precursor concentrations, the ZnO crystals were elongated along the c-axis, and the diameter of the {001} planes was reduced, leading to shape evolution from hexagonal disk to prismatic rod. As a result, the ZnO crystals were different from each other in the proportion of the {100} nonpolar planes and the {001} polar planes. The well-defined ZnO crystals were used as the cocatalyst with skeletal Ni40Mo10 in the combined reforming–hydrogenolysis (CRH) of glycerol in the absence of adventitious H2. A remarkable shape-dependent effect on the selectivity to the C3 hydrogenolysis products and the production rate of 1,2-propandiol (1,2-PDO) was identified. ZnO with a larger proportion of the nonpolar planes was more effective in the CRH of glycerol to the C3 products. An excellent linear relationship between the surface area of the {100} nonpolar planes and the production rate of 1,2-PDO was identified. This is attributed to the in situ enhancement of the Lewis acidity of the nonpolar planes of ZnO by chemisorbed CO2 from the reforming of glycerol, which greatly accelerates the dehydration of glycerol to acetol, the intermediate to 1,2-PDO.

    ABSTRACT: Partial hydrogenation of benzene to cyclohexene is attractive in terms of feedstock accessibility, atomic economy, and operational simplicity. Herein, a series of Ru/ZrO2 catalysts were prepared by post-treatment of a binary Ru–Zn/ZrO2 catalyst using 5–30 wt % NaOH aqueous solutions. Alloying between Ru and Zn was evidenced for the catalyst post-treated only by water (Ru/ZrO2-0). Alkaline post-treatment removed metallic Zn, forming smaller Ru nanoparticles. Concomitantly, the hydrophilicity of the catalysts was increased and maximized on the 10 wt % NaOH-treated catalyst (Ru/ZrO2-10). In partial hydrogenation of benzene, the Ru/ZrO2-0 catalyst displayed the highest turnover frequency but the lowest initial selectivity to cyclohexene, whereas the Ru/ZrO2-10 catalyst exhibited the highest initial selectivity (86 %) and yield of cyclohexene (51 %) among the catalysts investigated. A quantitative relationship between the initial selectivity to cyclohexene and the hydrophilicity of these catalysts was identified, which rationalizes the significant impact of alkaline post-treatment on selectivity enhancement in partial hydrogenation of benzene to cyclohexene over Ru/ZrO2 catalysts.

    ABSTRACT: The application of elaborately designed magnetic catalysts has long been limited to ease their separation from the products only. In this paper, we for the first time employed a magnetic sulphonated poly(styrene-divinylbenzene) resin catalyst on a magnetically stabilized-bed (MSB) reactor to enhance the etherification of fluidized catalytic cracking (FCC) light gasoline, one of the most important reactions in petroleum refining industry. We demonstrated that the catalytic performance of the magnetic acid resin catalyst on the magnetic reactor is substantially enhanced as compared to its performance on a conventional fixed-bed reactor under otherwise identical operation conditions. The magnetic catalyst has the potential to be loaded and unloaded continuously on the magnetic reactor, which will greatly simplify the current complex industrial etherification processes.

    ABSTRACT: The one-pot aqueous phase reforming (APR) and hydrogenolysis of glycerol to 1,2-propanediol (PDO) was catalyzed by physically mixed skeletal NiMo and zinc oxide catalysts in a continuous flow fixed-bed reactor without the aid of added H2. The skeletal NiMo catalyst alone is highly active towards glycerol but the selectivity for 1,2-PDO is only moderate. Physically mixing of MgO, SiO2, Al2O3, HZSM-5, TiO2, ZrO2, or CeO2 as a cocatalyst with skeletal NiMo was detrimental to the conversion of glycerol and yield of 1,2-PDO. However, physically mixing with ZnO gave an advantageous promoting effect on both the catalytic activity and selectivity for 1,2-PDO, and gave a 1,2-PDO yield of 52.0%, which is higher than that obtained with noble metal catalysts for the APR-hydrogenolysis of glycerol. The synergistic effect between physically mixed ZnO and skeletal NiMo was attributed to in situ enhancement of the Lewis acidity of ZnO by chemisorbed CO2 from the APR of glycerol on skeletal NiMo, which benefited both the dehydration of glycerol to acetol on ZnO and the hydrogenation of acetol to 1,2-PDO on skeletal NiMo.摘要以骨架NiMo以及与氧化物物理混合, 考察了其在连续固定床反应器中无外加氢气条件下的丙三醇一锅法重整–氢解制1,2-丙二醇(1,2-PDO)的性能. 研究发现, 骨架NiMo自身催化活性高, 但对1,2-PDO的选择性一般. 当将其与MgO, SiO2, Al2O3, HZSM-5, TiO2, ZrO2或CeO2机械混合时, 丙三醇转化率和1,2-PDO选择性均发生下降. 但当与ZnO物理混合时, 催化活性和选择性均有所提高, 1,2-PDO得率可达52.0%, 优于贵金属催化剂在该一锅法反应中得到的结果. 物理混合的ZnO与骨架NiMo之间这种独特的协同作用, 归因于重整过程中产生的CO2在ZnO上发生化学吸附, 原位增强了ZnO的路易斯酸性. 这不仅促进了丙三醇在ZnO上脱水生成中间产物丙酮醇, 也促进了丙酮醇在骨架NiMo上加氢生成1,2-PDO.

    ABSTRACT: Raney Ni is one of the most widely used catalysts in the petrochemical industry. This material's intrinsic catalytic activity for hydrogenation may be enhanced by transforming the crystalline Ni-based alloy into an amorphous structure via melt-quenching. The meta-stability and low specific surface area of such amorphous alloys, however, can severely restrict their catalytic applications. Our work has demonstrated that the incorporation of rare earth (RE) elements increases the crystallization temperature of an amorphous Ni catalyst by 200 K. Related experimentation has determined that the specific surface area of such catalysts is dramatically increased by two orders of magnitude following alloying with Al and subsequent caustic leaching. In addition, by introducing a third metal as a promoter, the hydrogenation selectivity, corrosion resistance and magnetism of these materials may be precisely adjusted, giving rise to a family of skeletal amorphous Ni alloy catalysts, to which we apply the trade name SRNA. Among these catalysts, the SRNA-1 catalyst is used for the hydrogenation of pharmaceutical intermediates, SRNA-2 is employed for the hydrogenation of glucose into sorbitol, SRNA-3 is effective in the adsorptive desulfurization of gasoline and diesel and SRNA-4 is used for the purification of caprolactam. In addition, the SRNA-5 catalyst is useful in the hydrogenation of benzoic acid as a partial substitute for the costly Pd/C catalyst, reducing consumption of the latter during the hydrogenation process by almost 50%.摘要Raney Ni催化剂是石油化学工业用量最大的催化剂之一, 通过急冷技术将其晶态结构转变为非晶态结构, 能够提高加氢活性. 但非晶态合金热稳定性差、比表面积小限制了这类催化材料的工业应用. 通过加入少量稀土元素, 使非晶态 Ni 晶化温度提高200 K以上; 通过加入Al再碱抽Al, 使非晶态Ni比表面积增加100倍以上; 通过加入功能助剂调节非晶态Ni的加氢选择性、增加抗酸碱腐蚀性和磁性, 从而形成了系列非晶态Ni加氢催化剂 (商品名为 SRNA). 其中, SRNA-1 用于药物中间体加氢; SRNA-2用于葡萄糖加氢制山梨醇; SRNA-3用于汽、柴油吸附脱硫; SRNA-4用于己内酰胺加氢精制; SRNA-5 用于苯甲酸加氢中替代Pd/C催化剂, 使后者的用量减少了50%.

    ABSTRACT: The new Ce‐promoted skeletal Fe catalysts with different Ce contents were prepared through alkali leaching of rapidly quenched ternary FeCeAl alloys and evaluated in the gas‐phase Fischer–Tropsch synthesis reaction. N2 physisorption and XRD analysis confirmed the function of Ce as a structural promoter. In the Fischer–Tropsch synthesis reaction, the incorporation of Ce markedly improved the activity and selectivity to C5+ hydrocarbons. Characterizations of the catalysts after Fischer–Tropsch synthesis confirmed the function of Ce as a chemical promoter. We also confirmed that the catalytic activity is associated with the concentrations of the surface polymeric and, to a lesser extent, atomic carbonaceous species and the C5+ selectivity correlated well with the surface concentration of Hägg carbide. We identified a linear relationship between the concentrations of the CeIII cations and Hägg carbide, which clearly substantiated the hypothesis that the chemical effect of Ce is mediated by the Fe0CeIII ensembles facilitating the formation of Hägg carbide.

    ABSTRACT: The first commercial application of the magnetically stabilized bed (MSB) reactor is discussed. The MSB reactor uses a magnetic catalyst in a uniform magnetic field to combine the many advantages of the fixed bed, slurry bed, moving bed, and fluidized bed reactors. An industrial MSB reactor requires a large and uniform magnetic field, which was obtained by optimizing the coil installation spacing and inserting magnetic grids in the reactor. It was used for the intensification of the hydrogenation processes by operating in the chain mode. By utilizing the excellent hydrogenation activity and magnetism of an amorphous Ni catalyst, a MSB reactor was developed for the hydrorefining of caprolactam. Five industrial units of 200–400 kt/a production capacity have been built since 2003. The use of the appropriate magnetic catalyst in the MSB reactor also enhanced activities in CO methanation, selective acetylene hydrogenation and olefin oligomerization. This technology gives new opportunities for process intensification.摘要介绍了磁稳定床反应器在国际上的首次工业应用, 它集成了浆态床、固定床、移动床和流化床等反应器的优点. 通过调整线圈间距、在反应器内设置磁隔栅构件, 实现了均匀磁场的放大; 绘制出磁稳定床反应器链式操作相图. 将非晶态 Ni 优异的加氢性能和磁性与磁稳定床反应器反应过程强化性能相结合, 实现了在己内酰胺加氢精制过程的工业应用, 并建成 5 套 20∼$40 万吨/年工业装置. 磁性催化剂与磁稳定床反应器相结合, 强化了甲烷化、乙炔选择性加氢和烯烃叠合等反应过程, 形成了新技术生长点.

    ABSTRACT: Robust iron‐on‐graphene catalyst The cover picture shows highly dispersed iron oxide nanoparticles anchored on reduced graphene oxide (rGO) with defects. In their Communication on p. 714 ff., B. Sun et al. demonstrate the one‐pot fabrication of such materials using different metal acetylacetonates and GO as starting materials. The outstanding stability of the small iron oxide nanoparticles on rGO is validated in high‐temperature reduction and in long‐term gas‐phase Fischer‐Tropsch synthesis. This work presents the promising future of the graphene‐related nanomaterials, even in very challenging high‐temperature applications by facile materials design.

    ABSTRACT: Ru–B/ZrO2 catalysts using monoclinic, amorphous, and tetragonal ZrO2 as supports were prepared and used for liquid-phase hydrogenation of benzene to cyclohexene. It is identified that both the Lewis acid sites and the Brønsted acid sites existed on monoclinic ZrO2 (ZrO2-M), while there were only Lewis acid sites on amorphous (ZrO2-A) and tetragonal ZrO2 (ZrO2-T). The amount of acid sites on ZrO2-T was the lowest. In liquid-phase hydrogenation of benzene to cyclohexene, the Ru–B/ZrO2-T catalyst exhibited the highest selectivity and yield of cyclohexene, with the maximum yield of cyclohexene being 47%. These results suggest that for ZrO2-supported Ru–B catalysts, the lower was the amount of acid sites on ZrO2, the higher was the selectivity to cyclohexene. Also, the presence of the Brønsted acid sites on ZrO2 is probably adverse to the selectivity toward cyclohexene.

    ABSTRACT: Amorphous alloys structurally deviate from crystalline materials in that they possess unique short-range ordered and long-range disordered atomic arrangement. They are important catalytic materials due to their unique chemical and structural properties including broadly adjustable composition, structural homogeneity, and high concentration of coordinatively unsaturated sites. As chemically reduced metal-metalloid amorphous alloys exhibit excellent catalytic performance in applications such as efficient chemical production, energy conversion, and environmental remediation, there is an intense surge in interest in using them as catalytic materials. This critical review summarizes the progress in the study of the metal-metalloid amorphous alloy catalysts, mainly in recent decades, with special focus on their synthetic strategies and catalytic applications in petrochemical, fine chemical, energy, and environmental relevant reactions. The review is intended to be a valuable resource to researchers interested in these exciting catalytic materials. We concluded the review with some perspectives on the challenges and opportunities about the future developments of metal-metalloid amorphous alloy catalysts.

    ABSTRACT: Heat transfer coefficients were measured by immersed probes in co- and counter-current G–L–S magnetically stabilized fluidized beds (MSFBs) using air, water and nickel-alloy particles as the gas, liquid and solid phases. Influences of major factors, including magnetic field intensity, superficial gas and liquid velocities, liquid viscosity and surface tension, on heat-transfer properties were studied experimentally, indicating that both co- and counter-current G–L–S MSFB can provide relatively uniform radial distribution of heat transfer coefficients under appropriate operation conditions, thus controlling operation temperature for highly exothermic multi-phase reaction systems. Two correlations were provided to estimate accurately heat transfer properties in both co- and counter-current G–L–S MSFB systems, with an average error of less than 10%.

    ABSTRACT: The effect of supercritical water (SCW) on the hydroconversion of Tahe residue has been investigated at different temperatures and hydrogen pressures. It was demonstrated that introduction of water into the reaction could reduce the amount of coke formed and increased the yield of liquid product. The isotopic tracer method was used to determine quantitatively the extent of hydrogen exchange between water and the liquid product. The results indicated that the degree of hydrogen exchange of the liquid product with water decreased slightly with increasing hydrogen pressure. About 40% of the water molecules involved in hydrogen exchange with the oil residue as the concentration of water in the reaction mixture was 10 wt %. © 2010 American Institute of Chemical Engineers AIChE J, 2010

    ABSTRACT: A rapidly quenched skeletal Ni (RQ Ni) prepared by the melt-spinning method followed by alkali leaching was used as a new category of Ni precursor to fabricate effective chiral Ni catalyst. A series of tartaric acid (TA)–NaBr–modified RQ Ni catalysts (MRQNi) were derived, and the textural and structural properties of the MRQNi catalysts were systematically investigated. It is found that the modification conditions influence profoundly the composition, texture, and Ni crystallite size of the MRQNi catalysts. In liquid phase hydrogenation of butanone to R-(−)-2-butanol, the optimized MRQNi catalyst exhibits much better activity and enantioselectivity than the similarly chirally modified Raney Ni catalyst. Based on the characterizations, the superior catalytic performance of the MRQNi catalyst is mainly attributed to the higher surface content of the sodium–nickel(II) tartrate complex than that on the chirally modified Raney Ni catalyst.

    ABSTRACT: We demonstrate a one-pot hydrothermal cohydrolysis-carbonization process using glucose and iron nitrate as starting materials for the fabrication of carbonaceous spheres embedded with iron oxide nanoparticles. It is verified by TEM, (57)Fe Mossbauer, and Fe K-edge XAS that iron oxide nanoparticles are highly dispersed in the carbonaceous spheres, leading to a unique microstructure. A formation mechanism is also proposed. This route is also applicable to a range of other naturally occurring saccharides and metal nitrates. A catalytic study revealed the remarkable stability and selectivity of the reduced Fe(x)O(y)@C spheres in the Fischer-Tropsch synthesis, which clearly exemplifies the promising application of such materials.
