Summary: This research proposes an efficient and low-cost method for the preparation of ZSM-5 zeolite, achieving high-value utilization of coal gasification coarse slag (CGCS). By one-step microwave synthesis, the desilication solution from CGCS is used as the major source material, leading to improved crystallization rate and specific surface area of ZSM-5 zeolite. The resulting high-purity ZSM-5 zeolite exhibits good crystallinity, smooth surface, and high adsorption capacity.

Summary: In this study, MFI-type cobaltosilicates were successfully synthesized using a novel pretreatment method, with optimal crystallization conditions determined through investigation of various parameters. Characterization techniques including XRD, FT-IR, and UV-vis confirmed the formation of pure crystalline ZSM-5 zeolites and the incorporation of Co2+ ions into the zeolites' framework. The synthesized Na[Co]ZSM-5 zeolites showed comparable specific surface areas to aluminosilicate ZSM-5 zeolites, and demonstrated CO2 adsorption capacities of approximately 2.19 and 5.33 mmol g(-1) at 298 K and 1 bar for samples prepared at pH = 9.5 and 10.5, respectively.

Summary: New mixed matrix membranes (MMMs) of poly(styrene-butadiene-styrene) (SBS) incorporated with hydrophobic ZSM-5 zeolite (calcinated and non-calcinated) were prepared and characterized. The membranes showed improved separation performance, with an increase in temperature leading to higher permeation flux and lower separation factor. The sample with 20 wt% calcinated zeolite (C.ZSM-5) exhibited the highest separation factor.

Summary: Micellization of zeolite precursor seeds with surface passivating organosilane groups is an effective technique to reduce crystallite aggregation and produce hierarchically porous materials with additional mesopores. By changing the synthesis environment of the surface passivation process, the average particle size and pore architecture of the zeolite can be altered. Using low hazard organic solvents with different hydrophobicities as a matrix for surface organosilanization and crystallization processes has shown promising results in this study.

Summary: This passage describes the interaction between a photon source and an absorber in a rotating waveguide, where the absorber absorbs the emitted photons, resulting in a decrease in the number of photons detected by a detector. By calculating different configurations, the frequency shifts are determined, revealing that even when the source and absorber are at rest, there is a nonzero frequency shift.

Summary: In this study, molecular simulations were used to identify the most suitable zeolite structure for separating a feed stream containing 90 mol.% propylene and 10 mol.% propane. It was found that the temperature swing adsorption (TSA) process is more favorable due to the effect of temperature on the molar loading.

Summary: The performance of ZrO2-supported Fe2O3 mesoporous catalysts with different weight percentages of Fe in propane dehydrogenation process was studied. The catalysts with an optimum Fe loading of 12 wt % showed the best results in terms of propane conversion and propylene selectivity. Active Fe3+ species and Zr4+ strong acid sites played important roles in propylene production and side reactions, respectively. Increasing the iron species on ZrO2 improved the catalyst stability. The presence of CO2 enhanced the catalyst stability through reoxidation of active Fe3O4 species and coke removal.

Summary: In this research, the feasibility of revamping the simulated moving bed for paraxylene separation was studied using industrial Ba-faujasite exchanged adsorbent. The study focused on changing the operating conditions to optimize the separation of meta-xylene. Experimental and theoretical analyses were conducted, considering different mixed-xylene feed cases. The results showed that the presence of para-xylene in the feed did not significantly change the selectivity of the adsorbent towards meta-xylene, but in certain conditions, the selectivity of meta-xylene was higher than ortho-xylene and ethylbenzene. The study also involved the design and simulation of a real industrial SMB plant to evaluate its performance in meta-xylene separation, achieving a purification rate of 83.91%. By considering additional distillation towers, the purity of meta-xylene reached 96%. The economic investigation indicated that the process is economically viable with a feed cost of $700/ton.
