ZSM-5 Series Shape-selective Zeolites
ZSM-5 zeolite inogona kushandiswa petrochemical indasitiri, yakanaka makemikari indasitiri uye mamwe minda nekuda kwayo yakakosha matatu-dimensional muchinjiko wakatwasuka pore canal, yakakosha chimiro-selective crackability, isomerization uye aromatization kugona. Parizvino, anogona kuiswa kune FCC catalyst kana additives inogona kuvandudza peturu octane nhamba, hydro/aonhydro dewaxing catalysts uye unit process xylene isomerization, toluene disproportionation uye alkylation. Iyo peturu octane nhamba inogona kukwidziridzwa uye iyo olefin yemukati inogona zvakare kuwedzerwa kana mazeolite akawedzerwa kune FCC catalyst muFBR-FCC reaction. Mukambani yedu, ZSM-5 serial shape-selective zeolites ine silica-alumina ratio yakasiyana, kubva ku25 kusvika ku500. Kugoverwa kwechidimbu kunogona kugadziriswa maererano nezvinodiwa nevatengi. Iyo isomerization kugona uye kugadzikana kwechiitiko kunogona kushandurwa kana iyo acidity ichigadziriswa nekuchinja silica-alumina reshiyo zvinoenderana nezvaunoda.
