ZSM-5 Series Zeolites xaiv cov duab
ZSM-5 zeolite siv tau rau kev lag luam petrochemical, kev lag luam tshuaj zoo thiab lwm yam teb vim nws muaj qhov tshwj xeeb peb-seem hla ncaj pore canal, tshwj xeeb zoo li-xaiv crackability, isomerization thiab aromatization muaj peev xwm. Tam sim no, lawv tuaj yeem siv rau FCC catalyst lossis additives uas tuaj yeem txhim kho tus lej octane roj av, hydro/aonhydro dewaxing catalysts thiab unit process xylene isomerization, toluene disproportionation thiab alkylation. Tus lej octane roj av tuaj yeem txhim kho thiab cov ntsiab lus olefin kuj tuaj yeem nce ntxiv yog tias cov zeolites raug ntxiv rau FCC catalyst hauv FBR-FCC reaction. Hauv peb lub tuam txhab, ZSM-5 serial zoo li-xaiv zeolites muaj silica-alumina piv sib txawv, txij li 25 txog 500. Kev faib tawm ntawm cov khoom me me tuaj yeem hloov kho raws li cov neeg siv khoom xav tau. Lub peev xwm isomerization thiab kev ua haujlwm ruaj khov tuaj yeem hloov pauv thaum acidity raug kho los ntawm kev hloov silica-alumina piv raws li koj xav tau.
