    ABSTRACT: The article presents the results of catalytic and surface properties of pure zinc oxide synthesized by hydrothermal method and surface-doped with gold nanoparticles. As a test reaction, the catalytic transformation of n-butyl alcohol towards the dehydrogenation or bimolecular condensation of symmetric ketone or an ester was studied. The tested materials catalyse both consecutive reactions, wherein the transformation towards the ketone is dependent on the presence of surface oxygen vacancies, whose concentration depends on the temperature. In turn, the transformation to the ester occurs in the presence of gold nanoparticles deposited on the surface of zinc oxide. The difference in work function of electrons from these materials create a change in the electron concentration in the surface area and will shift the balance of the coupling reaction of hydrogen with lattice oxygen, which prefers the formation of aldehyde and ester. The results were compared with the catalytic properties of other previously studied oxide systems in this group of changes. This analysis enabled the development of the mechanism of transformation and explanation of the impact of gold on the kinetics of the process.

    ABSTRACT: The current soot oxidation catalyst scenario has been reviewed, the main factors that affect the activity of powder catalysts have been highlighted and kinetic soot oxidation models have been examined. A critical review of recent advances in modelling approaches has also been presented in this work. The multiscale nature of DPFs lends itself to a hierarchical organization of models, over various orders of magnitude. Different observation scales (e.g., wall, channel, entire filter) have often been addressed with separate modelling approaches that are rarely connected to one another, mainly because of computational difficulties. Nevertheless, DPFs exhibit an intrinsic multi-scale complexity that is reflected by a trade-off between fine and large-scale phenomena. Consequently, the catalytic behavior of DPFs usually results in a non-linear combination of multi-scale phenomena.

    ABSTRACT: The SiO2 supported Ni2P catalysts were prepared by H2 temperature-programmed reduction (TPR) or plasma reduction (PR) of two precursors, which were obtained by co-impregnation of SiO2 with (NH4)2HPO4 and Ni(NO3)2·6H2O with and without calcination. Their catalytic performances were evaluated by the hydrodenitrogenation of quinoline. The catalysts prepared by the TPR method showed a higher denitrogenation activity at low temperature (≤320 °C) but a lower denitrogenation activity at high temperature (≥340 °C) relative to those prepared by the PR method. The results of CO chemisorption and XPS analysis suggest that this can be explained that more metallic Ni species were present in the surface of the catalysts prepared by the TPR method, which enhanced their hydrogenation activity at temperatures below 340 °C. Calcination of the precursor is not necessary for the preparation of Ni;bsubesubbsubesub. However, both the dispersion and the surface composition of the Ni2P phase were affected by the calcination and reduction approaches.

    ABSTRACT: A series of activated γ-alumina supported Mo/Co catalysts with different Mo loadings ranging from 8 to 20 wt.% have been prepared through the impregnation by soaking metal precursors over the alumina support followed by drying (120 °C) and calcination (350, 400 and 600 °C) for the fabrication of catalytic membrane. A comparative study on activated and γ-Al2O3with low surface area has been performed to understand the metal-support interaction and to select the suitable support in terms of metallic dispersion (MD) and metallic surface area (MSA) for better catalytic activity. Several characterization techniques, such as, BET surface area, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy (FESEM), electron spin resonance (ESR), temperature-programmed reduction (TPR), laser Raman spectroscopy (LRS), transmission electron micrograph (TEM), Energy dispersive X-ray (EDX) spectroscopy and CO chemisorption have been used to verify the interaction between Mo and activated γ-alumina. Based on characterization, 16% Mo–Co/activated γ-Al2O3 catalyst calcined at 400 °C is optimized and selected for activity test. Claus reaction has been chosen to study the catalytic activity. Overall as well as individual conversion of both H2S and SO2, selectivity and yield of product are measured in this study. The highest turnover frequency (TF) is observed as 3.80 min−1 at 300 min for the optimized catalyst.

    ABSTRACT: The gradually increasing demand on 1,3-butadiene (BD) requires alternative production routes. Catalytic oxidative dehydrogenation of 1- butene to BD using CO2 as soft oxidant was proved as a potential process and thus systematically studied over Fe2O3/Al2O3 catalysts. It was found that the loaded Fe2O3 promotes oxygen mobility and modifies the surface acidity of Al2O3, leading to a higher 1-butene conversion and BD selectivity; the highest ones were obtained on 20 wt.% Fe2O3/Al2O3 at 600°C. The in situ Diffuse Reflectance Infrared Fourier Transform Spectroscopy studies revealed that CO2 is essential to promote the activation of 1-butene on the Fe2O3 catalysts and thus BD production.

    ABSTRACT: Monolith or foam substrates were coated with various Pd/C suspensions by the washcoating method. The resulting structured catalysts were characterized by thermal analysis (TGA), physisorption of nitrogen (BET method) and electron microscopies (SEM and TEM). Their catalytic activity was evaluated in the model reaction of nitrobenzene hydrogenation. It was found that depending on the carbon source (carbon black, activated carbon or carbon nanotubes), the Pd/C deposits were more or less resistant to the coating procedure. All the samples were adherent to the substrates, but only Pd/MWCNT was still highly active after coating. The one-step deposition of nanotubes-based catalysts does not alter significantly the catalytic properties of the catalyst and is a promising alternative to nanotube layers grown in situ.

    ABSTRACT: A high Zr-loaded SBA-15 mesoporous material with high surface area, well-ordered structure, homogeneous Zr dispersion and high surface acidity has been prepared by a novel direct-post synthesis technique (DP). While maximum Zr loadings of 5.1 wt% and 16.7 wt% have been achieved in direct and post synthesis methods, respectively, the support synthesized by the DP method (ZrSBADP2) has yielded a Zr loading of 32.1 wt%. Also, a high acidity of 136 μmol g-1, favorable for catalysis reactions, has been reached for ZrSBADP2. The effect of cobalt concentration on the catalyst has also been examined on the NO to N2 conversion via selective reduction (C3H8-SCR) with propane. It has been demonstrated that the catalyst with 2 wt% cobalt has shown the highest N2 yield (70%) at 400°C in the presence of 6 vol% O2. The catalyst performance has significantly improved in the presence of water vapor where the N2 yield increased to 54% and 70% at 300°C and 350°C, respectively, compared with 18% and 34% in the absence of water vapor. Also, at high temperatures (≥400°C), the presence of water vapor has not resulted in any decrease in the catalyst performance. The long term stability test has proved that the catalyst structure is retained in extreme prolonged reaction conditions, making it a suitable catalyst for real applications.
