ZSM-5 Series Apẹrẹ-aṣayan Zeolites
Zeolite ZSM-5 le ṣee lo fun ile-iṣẹ petrochemical, ile-iṣẹ kemikali ti o dara ati awọn aaye miiran nitori pataki agbelebu onisẹpo mẹta ti o tọ lila pore, pataki apẹrẹ-yan yiyan, isomerization ati agbara aromatization. Ni lọwọlọwọ, wọn le lo si ayase FCC tabi awọn afikun ti o le mu nọmba octane petirolu dara si, awọn olutọpa hydro/aonhydro dewaxing ati ilana iṣojuuwọn xylene isomerization, disproportionation toluene ati alkylation. Nọmba octane petirolu le ni ilọsiwaju ati pe akoonu olefin le tun pọ si ti a ba ṣafikun awọn zeolites si ayase FCC ni iṣesi FBR-FCC. Ninu ile-iṣẹ wa, awọn zeolites ZSM-5 ni tẹlentẹle apẹrẹ-aṣayan ni oriṣiriṣi silica-alumina ratio, lati 25 si 500. Pipin patiku le tunṣe ni ibamu si awọn ibeere awọn alabara. Agbara isomerization ati iduroṣinṣin iṣẹ le yipada nigbati acidity ti tunṣe nipasẹ yiyipada ipin silica-alumina gẹgẹbi awọn ibeere rẹ.
