摘要： A method for removing hydrogen sulfide (H2S) from a H2S-containing gas composition, including charging an aqueous media to a reactor under continuous agitation, dispersing particles of a composite in the aqueous media to form a composite mixture, continuously agitating the composite mixture, introducing the H2S-containing gas composition to the reactor containing the composite mixture under continuous agitation and passing the H2S-containing gas composition through the composite mixture, and adsorbing and removing H2S from the gas composition by the composite mixture to form a purified gas composition. The composite contains a CuMnAl mixed metal oxide (MMO) and zeolitic imidazolate framework-67 (ZIF-67) nanoparticles. The ZIF-67 nanoparticles are dispersed between layers of the CuMnAl MMO.

摘要： The present invention relates to a process for preparing fluid catalytic cracking (FCC) catalysts having porosity and accessibility controlled by the activity of water-soluble porogens. The catalyst produced can be used as an additive for fluid cracking, as additives for SOx and NOx reduction, as a combustion promoter and reduction of sulfur in cracked naphtha. It can also be used in hydrocracking, as a support for hydrotreating catalysts, catalytic pyrolysis of post-consumer polymers (rubber tires, plastic films, and so on) and pyrolysis of biomass.
