Ama-Zeolite akhetha ukuma kochungechunge lwe-ZSM-5
I-ZSM-5 zeolite ingasetshenziselwa imboni ye-petrochemical, imboni yamakhemikhali amahle kanye neminye imikhakha ngenxa yomsele wayo okhethekile we-three-dimensional cross straight pore, ukuqhekeka okukhethekile kokukhetha ukuma, i-isomerization kanye nekhono le-aromatization. Okwamanje, zingasetshenziswa ku-catalyst ye-FCC noma izithasiselo ezingathuthukisa inombolo ye-octane kaphethiloli, ama-catalyst e-hydro/aonhydro dewaxing kanye ne-unit process xylene isomerization, i-toluene disproportionation kanye ne-alkylation. Inombolo ye-octane kaphethiloli ingathuthukiswa futhi okuqukethwe kwe-olefin kungakhushulwa uma ama-zeolite engezwa ku-catalyst ye-FCC ku-FBR-FCC reaction. Enkampanini yethu, ama-zeolite e-ZSM-5 serial shape-selective anesilinganiso esihlukile se-silica-alumina, kusukela ku-25 kuya ku-500. Ukusatshalaliswa kwezinhlayiya kungalungiswa ngokuya ngezidingo zamakhasimende. Amandla e-isomerization kanye nokuzinza komsebenzi kungashintshwa lapho i-acidity ilungiswa ngokushintsha isilinganiso se-silica-alumina ngokuya ngezidingo zakho.
