    ABSTRACT: Polymer nanocomposites with layered silicates have two different types of interface sites: edges with hydroxyl groups and gallery faces with oxygen atoms. The polymer-particle interface at either site may be strengthened by silane coupling agents. The objective of this work was to investigate the morphology and rheology in the melt-compounded state and the reprocessed state of polypropylene-layered-silicate nanocomposites with reactive coupling by the silane and a long chain polymeric compatibilizer at different interface sites. Two different organically modified layered silicates with different aspect ratios and surfactants were treated with an aminoalkyldimethoxy silane; in one case, the silanols reacted only at the nanolayer edges while in the other case, the silanes entered the interlayer galleries. The effect of reactive coupling in both cases was noticeably improved dispersion with thinner stacks of nanolayers. The uniaxial extensional viscosity of these melts displayed greater strain hardening and more so in the case of reactive coupling at both faces and edges despite the aspect ratio of this organoclay being significantly lower. Upon reprocessing, while some degradation of the polymer matrix occurred in all cases, the effects on the nanostructure were quite different just as the effects on the rheology of the melts were quite different. These effects may be attributed to differing changes in the fraction of particle-attached polymer chains entangling with free polymer chains.

    ABSTRACT: One dimensional pore zeolites such as ZSM-22 (TON) are potential catalysts for hydrocarbon conversion reactions, including methanol-to-propylene (MTP) reaction. Different crystal lengths of ZSM-22 zeolite were prepared and examined for the MTP reaction. Nanosized TON zeolites with crystal length of ∼100 nm were synthesized by dynamic hydrothermal synthesis. The zeolite crystal length was tuned by using ethylene glycol as crystal growth modifier. The crystal lengths of ZSM-22 zeolites (approximately 100 and 300 nm) were confirmed from FE-SEM and TEM micrographs. However, the textural properties such as BET surface area and crystallinity of crystals were fairly similar. The effect of ZSM-22 crystal length on catalytic activity and propylene yields in the methanol-to-propylene reaction was investigated. The TON nanocrystals resulted in a higher propylene yield and better catalytic stability compared to the submicrometer zeolite (∼300 nm). Deactivation was observed for all catalysts. However, longer lifetime was observed for the nanosized ZSM-22 with crystal length of ∼100 nm.

    ABSTRACT: The volatility of the global oil market, coupled with increasing levels of greenhouse gas (GHG) emissions, has sparked the search for alternative methods for the production of liquid transportation fuels from domestically available carbon-based resources. The United States has three feedstocks available to gradually replace petroleum as its primary energy source, namely: coal, biomass, and natural gas. The major contributions to the production of liquid fuels from these three feedstocks have been highlighted in a recent review [1]. Hybrid energy systems utilizing coal and biomass have been the center of interest in recent years. Coal has a lower delivered cost than biomass, but conventional coal-to-liquids (CTL) refineries result in almost twice the life-cycle GHG emissions of a petroleum-based plant. Biomass, however, has the ability to reduce greenhouse gas emissions through the capture of CO2 during photosynthesis. The economic and environmental benefits that both these feedstocks offer can be exploited by investigating coal-and-biomass-to-liquid fuels (CBTL) systems. Using an optimization-based process synthesis framework, the thermochemical conversion of coal and biomass will be presented [2]. Synthesis gas (syngas) will be generated via gasification of the biomass and coal feedstocks through separate gasification units. The syngas can then be directed to either a dedicated water-gas-shift reactor or passed directly to the scrubbing system. Hydrocarbon production will proceed through either Fischer-Tropsch synthesis or methanol formation. The Fischer-Tropsch hydrocarbons can be upgraded over a ZSM-5 reactor or through a series of treatment units that will produce distillate and gasoline-range products. The methanol can be passed to the methanol-to-gasoline (MTG) process or to the methanol-to-olefins/olefins-to-gasoline-and-distillate (MTO/MOGD) processes. Simultaneous heat and power integration is included in the model to convert waste heat into electricity. The optimal process topology that can produce gasoline, diesel, and kerosene at the lowest cost is determined using rigorous deterministic global optimization and process synthesis strategies [3-13]. This study presents a baseline so that a fair comparison between different process alternatives can be made. Multiple case studies are presented to investigate the effect of plant capacity and product distribution on the overall cost of the refinery, the process topology, the total plant cost, and the break-even oil price. The results demonstrate that coal and biomass refineries can become economically competitive with petroleum-based processes while simultaneously reducing life-cycle greenhouse gas emissions.

    ABSTRACT: Decomposition of gaseous NH3 from ammonia (NH3)-containing wastewater was explored using Ni-loading Al2O3 catalysts. The thermochemical decomposition of an NH3/steam mixture (wet-NH3) with different steam contents at 873, 923, and 973 K using a fixed-bed reactor under ambient pressure. The present results indicated that the catalysts can be deactivated by the formation of NiAl2O4, which can be thermodynamically generated, and confirmed that the extent of deactivation was greatly affected by the partial pressure of the steam (PH2O). The catalytic activities at 873 K decreased with increasing PH2O, whereas the activity was constant above PH2O of 25 kPa. However, the NH3 conversion was almost independent of the NH3 flow rate and temperature, and ∼30% of the NH3 was decomposed at each temperature. This study indicated that, even in the presence of steam, this catalyst could decompose NH3 from NH4+-containing water.

    ABSTRACT: A comprehensive investigation of wastewater treatment operation is provided through utilization of a validated dynamic model, historical data from a real plant, and bifurcation theory. Bifurcation analysis was carried out with wastewater flow rate, stormwater flow rate, airflow rate, water temperature, and influent ammonia concentration as the free parameters. A two-parameter continuation using airflow rate and water temperature simultaneously was also performed. Results indicate an overall robustness of the plant toward disturbances, which comes at the cost of excessive energy usage. Even then, transients caused by those disturbances are inevitable and can cause violations of regulatory permits on effluent ammonia and dissolved oxygen concentrations. Another important finding is the excessive air usage in aeration tanks, which can be cut by 50% on average without affecting the effluent quality.

    ABSTRACT: In this study, multiwalled carbon nanotubes were successfully modified using poly propyleneimine dendrimer. Structural characterization of the newly synthesized adsorbent confirmed the modification of nanotubes by dendrimer molecules. In order to evaluate the performance of this novel adsorbent for the removal of two direct dyes from textile wastewaters, the effect of important parameters including pH, initial dye concentration, adsorbent dosage, and inorganic salts was investigated in single and binary dye solutions. Response surface methodology was employed to find the relation between the effective parameters and dye removal efficiency. The adsorption process was optimized to reach the dye removal of 95% using response optimizer. The prepared adsorbent showed excellent adsorption behavior toward the anionic dye molecules, and the dye removal efficiencies of nanotubes were significantly improved from 17.7% to 99.9% after their modification with dendrimer. Also, the desorption tests revealed the maximum dye release of 44.01%.
