Several chemicals, such as pesticides and heavy metals, are frequently encountered together in environment matrices, becoming a priority concerning the prevention of their emissions, well removal from environment. In this sense, work aimed to evaluate effectiveness permeable biosorbent bio-barrier reactor (PBR) on atrazine metals (copper zinc) aqueous solutions. The was built with bacterial bio...

Abstract Advanced thermal energy storage technologies based on physical adsorption and chemical reactions of thermochemical materials (TCMs) are capable storing large shares renewable with high density. Further research development is required to improve the performance reduce cost these materials. A promising approach developing low-cost TCM use natural zeolite adsorbents as host matrices in s...

We employ a synergistic material and process development strategy to improve the performance of single-cycle vacuum pressure swing adsorption (VPSA) for hydrogen purification CO2 separation from reforming-based synthesis. Based on process-informed adsorbent selection criteria, including high cyclic capacity selective uptake impurities like CO, N2, CH4 over H2, metal organic framework (MOF), Cu-...

BACKGROUND Cyclohexyl acetate and acetone are used as environmentally friendly solvents, while isobutene acts an intermediate in the production of methacrolein, ethers, plastics pharmaceuticals. Two La-zeolite catalysts have been studied for converting acetic acid to cyclohexyl acetate, isobutene. RESULTS La-based zeolites were synthesized from Na-nFAU by ammonium ion exchange, followed lanthan...
