Zeolites nke usoro ZSM-5 nwere ụdị Zeolites
Enwere ike iji zeolite ZSM-5 mee ihe maka ụlọ ọrụ petrochemical, ụlọ ọrụ kemịkalụ dị mma na mpaghara ndị ọzọ n'ihi ọwa oghere pore atọ dị iche iche, ike mgbawa pụrụ iche maka ọdịdị, isomerization na aromatization. Ugbu a, enwere ike itinye ha na ihe mgbakwunye FCC nke nwere ike imeziwanye ọnụọgụ octane gasoline, ihe na-akpali hydro/aonhydro dewaxing na unit process xylene isomerization, toluene disproportionation na alkylation. Enwere ike imeziwanye ọnụọgụ octane gasoline ma nwee ike ịbawanye ọdịnaya olefin ma ọ bụrụ na etinyere zeolites na ihe na-akpali FCC na mmeghachi omume FBR-FCC. N'ụlọ ọrụ anyị, zeolites ZSM-5 serial shape-selective nwere nha silica-alumina dị iche iche, site na 25 ruo 500. Enwere ike ịgbanwe nkesa ihe dị na ya dịka ihe ndị ahịa chọrọ si dị. Enwere ike ịgbanwe ikike isomerization na nkwụsi ike ọrụ mgbe agbanwere acidity site na ịgbanwe nha silica-alumina dịka ihe ị chọrọ si dị.
