Molekụla myọ ZSM

ZSM-5 ụdị zeolite, nke elu-silica zeolite na-enwe a Si / Al ruru nke ruo 1000 na n'elu, na-egosi hydrophobic e ji mara. Ọdịdị atụmatụ nke ndị dị otú ahụ a zeolite bụ na vetikal na kehoraizin akụkụ bụ crystalline alum inosilicate esịnede 10-membered ọwa. Ihe owuwu na-emi esịnede asatọ 5-membered yiri mgbaaka, nke nwere ọwa na na na-enweghị onu-free cavities. ZSM-5 nwere ihe abụọ tent nke cross ọwa, otu onye nke bụ ellipse, na window n'obosara-ya bụ 0,55 ka 0.60nm. Dị ka mmeghachi omume ohere bụ yiri udi nke ohere, ndị zeolite nwere a udi nhọrọ mmetụta na reactants na ngwaahịa. Ọzọkwa, ZSM-5 bụ ezigbo akụrụngwa nke nhọrọ mkpali n'ihi na adabako Ọdịdị na hydrothermal kwụsie ike.

ZSM-5 ụdị zeolite na-ebe etinyere Petrochemical nhazi ọrụ, etinyere na fluidifying, catalyzing na cracking usoro dị ka otu nnyemaaka maka amị ọzọ propylene na gasị gas, na rụọ ọrụ ndị octane nọmba nke mmanụ ụgbọala. Ke adianade do, zeolite nwere ike etinyere na mmepụta nke ethylbenzene, xylene, phenol, pyridine, wdg
