ZSM-5 zeolite e ne e ka sebelisoa bakeng sa indasteri ea petrochemical, indasteri e ntle ea lik'hemik'hale le masimo a mang ka lebaka la phanele ea eona e khethehileng ea likarolo tse tharo tse otlolohileng tsa pore canal, mokhoa o ikhethileng oa ho khetha sebopeho, bokhoni ba isomerization le monko o monate. Hajoale, li ka sebelisoa ho catalyst ea FCC kapa li-additives tse ka ntlafatsang nomoro ea octane ea peterole, li-catalysts tsa hydro/aonhydro dewaxing le unit process xylene isomerization, toluene disproportionation le alkylation. Nomoro ea octane ea peterole e ka ntlafatsoa mme litaba tsa olefin le tsona li ka eketsoa haeba li-zeolite li eketsoa ho catalyst ea FCC karabelong ea FBR-FCC. K'hamphaning ea rona, li-zeolite tsa serial shape-selective zeolite tsa ZSM-5 li na le karo-karolelano e fapaneng ea silica-alumina, ho tloha ho 25 ho ea ho 500. Kabo ea likaroloana e ka fetoloa ho ea ka litlhoko tsa bareki. Bokhoni ba isomerization le botsitso ba ts'ebetso bo ka fetoloa ha acidity e fetoloa ka ho fetola sekhahla sa silica-aluminium ho latela litlhoko tsa hau.
