Summary: This study explores the feasibility of using a catalytic membrane reactor for ethylene production from ethane dehydrogenation. The use of a palladium-silver membrane to remove hydrogen from the reaction zone has significantly increased the conversion rate. The ultimate ethane conversion achieved was 22.2%. The addition of benzene hydrogenation as an auxiliary reaction improved the conversion rate to nearly 99%. Two new processes for ethylene production were developed, one of which does not require a refrigeration cycle system.

Summary: Boron-based nonmetallic materials are promising catalysts for selective oxidation of light alkanes. Hexagonal BN exhibits high selectivities and requires an induction period during methane oxidation. It acts as a radical generator, triggering gas-phase radical reactions, in contrast to surface reactions on B2O3/Al2O3 catalysts. The methyl radical is identified as the primary reactive species, and the moderate H-abstraction ability of CH3· radicals contributes to the excellent anti-overoxidation ability of boron-based catalysts.

Summary: The study found that increasing the SiO2/Al2O3 molar ratio of HY zeolites decreases the total amount of acid sites per unit area, leading to a reduced initial glycerol conversion; however, the initial acrolein selectivity increases with the higher Brønsted/Lewis acid sites ratio. The catalyst lifetime depends on pore structure, with larger surface areas improving deactivation rate constants.

Summary: In this study, it was found that Cr6+ species bonded to silanol groups in the zeolite framework can inhibit coke deposition during LDPE cracking. The Cr6+ species generate hydrogen from alkane products, while zeolitic acid sites catalyze the hydrogenation and decomposition of aromatics, resulting in reduced coke deposition. The synergistic effect of Cr6+ species and zeolitic acid sites allows for coke reduction without decreasing cracking activity.

Summary: The study introduces bimetallic catalysts to control the paraffin-to-olefin ratio in the conversion of dimethyl ether to high-octane hydrocarbons. The Cu-Zn/BEA catalyst showed higher dehydrogenation activity, resulting in a lower P/O ratio, while the Cu-Ni/BEA catalyst exhibited increased hydrogenation activity, leading to a higher P/O ratio. The product from Cu-Zn/BEA had the highest efficiency merit value among the three BEA catalysts compared to finished gasolines and alkylate blendstock.

Summary: The study reveals the improved catalytic properties of steamed zeolites for hydrocarbon activation. It shows that during steaming, aluminum oxide clusters with properties similar to hydroxylated transition alumina surfaces evolve in the zeolitic micropores. The number of Bronsted acid sites decreases during steaming, but the activity for alkane cracking and dehydrogenation increases due to the heterolytic C-H bond breaking on Al-O sites of aluminum oxide clusters confined in zeolitic pores.

Summary: Pre-treatment is crucial in enhancing cellulose accessibility from lignocellulosic biomass like empty fruit bunch. Ozonolysis pre-treatment is a green alternative for isolating cellulose from EFB. A diffusion-reaction model of EFB ozonolysis in a novel reactor was developed, showing larger biomass particles consume more ozone and have faster delignification rates. Computational simulations revealed that larger particles have lower ozone velocity but higher surface concentration.

Summary: The study uses the total Gibbs free energy minimization approach to analyze the thermodynamic equilibrium analysis of bio-oil model compounds to light hydrocarbons. Co-cracking of model compounds with methanol and ethanol at different temperatures and pressures revealed methane as the primary product, followed by hydrogen, carbon monoxide, carbon dioxide, and propionic acid. The production of light hydrocarbons was minimal, but ethanol had a significant effect on methane, ethylene, and propylene production.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
