Li-catalyst tsa Zeolite li bapala karolo ea bohlokoa indastering ea petrochemical, ho tsamaisa lits'ebetso tse fapaneng tsa lik'hemik'hale joalo ka ho phatloha ho hoholo, hydrocracking le isomerization. Har'a mefuta e mengata ea li-zeolite, ZSM le ZSM23 li bohlokoa haholo bakeng sa thepa ea tsona e ikhethang le lits'ebetso. Sengoliloeng sena, re tla hlahloba bohlokoa ba li-zeolite tsa ZSM le ZSM23, litšoaneleho tsa tsona, le phello ea tsona lekaleng la petrochemical.
ZSM le ZSM23 ke litho tsa lelapa la zeolite, e leng lisebelisoa tsa kristale, tse nyenyane tse nang le sebopeho sa moralo oa likarolo tse tharo. Li-zeolite tsena li entsoe ka silicon, aluminium, le liathomo tsa oksijene, tse etsang marang-rang a likanale le li-cavities tse lumellang hore ho be le khetho e khethehileng le catalysis ea limolek'hule. Sebopeho se ikhethileng sa pore le acidity ea ZSM le ZSM23 li li etsa li-catalyst tse sebetsang haholo bakeng sa karabelo e fapaneng ea petrochemical.
Li-zeolite tsa ZSM, ho kenyeletsoa le ZSM23, li tsebahala ka acidity ea tsona e phahameng le khetho ea sebopeho, e li nolofalletsang ho kenya letsoho phetohong ea limolek'hule tse kholo tsa hydrocarbon hore e be lihlahisoa tse nyane, tse bohlokoa haholo. Thepa ena e na le molemo ka ho khetheha molemong oa ho qhekella, mokhoa o sebelisoang ho arola li-hydrocarbon tse boima hore e be likaroloana tse bobebe joalo ka peterole le diesel. ZSM23, mofuta o ikhethileng oa ZSM zeolite, e bonts'a ts'ebetso e ntlafalitsoeng ea matla le khetho, e e etsa mothusi oa bohlokoa bakeng sa lits'ebetso tsa ntlafatso.
E 'ngoe ea lits'ebetso tsa bohlokoa tsa ZSM le ZSM23 zeolite ke tlhahiso ea peterole e phahameng ea octane ka isomerization ea naphtha e bobebe. Isomerization e kenyelletsa ho hlophisa bocha sebopeho sa limolek'hule tsa hydrocarbon ho ntlafatsa maemo a bona a octane, 'me ZSM le ZSM23 zeolite li sebelisoa ho tsamaisa ts'ebetso ena ka lebaka la bokhoni ba tsona ba ho fetolela li-hydrocarbon tse otlolohileng hore e be li-isomers tse nang le makala, tse nang le linomoro tse phahameng tsa octane.
Ho feta moo, li-zeolite tsa ZSM le ZSM23 li sebelisoa ho hydrocracking, e leng mokhoa o fetolang li-hydrocarbon tse boima hore e be lihlahisoa tse bobebe, tse bohlokoa joalo ka peterole, diesel le mafura a jet. Khetho ea sebopeho sa li-zeolite tsena e lumella ho phunyeha ho khethehileng ha li-hydrocarbon tse telele, tse hlahisang tlhahiso ea mafura a boleng bo phahameng a nang le thepa e ntlafetseng.
Ntle le karolo ea bona ts'ebetsong ea ho hloekisa, ZSM le ZSM23 zeolite li boetse li sebelisoa ho hlahiseng li-intermediate tsa petrochemical le lik'hemik'hale tse khethehileng. Bokhoni ba bona ba ho susumetsa karabelo e fapaneng, joalo ka alkylation le aromatization, e etsa hore e be tsa bohlokoa haholo ho kopantseng metsoako ea bohlokoa e sebelisoang tlhahisong ea lipolasetiki, li-detergents le lihlahisoa tse ling tsa indasteri.
Thepa e ikhethang ea ZSM le ZSM23 zeolite e etsa hore li batloe haholo indastering ea petrochemical. Sebaka sa tsona se phahameng, sebopeho sa pore, le asiti li kenya letsoho ts'ebetsong ea tsona e ikhethang, e nolofalletsang phetoho e sebetsang ea li-hydrocarbon hore e be lihlahisoa tsa bohlokoa. Ho feta moo, botsitso ba bona ba mocheso le lik'hemik'hale li etsa hore e be li-catalyst tse tšoarellang tse loketseng maemo a boima a mekhoa ea petrochemical.
Ntlafatso le ntlafatso ea li-zeolite tsa ZSM le ZSM23 e bile taba ea lipatlisiso tse batsi le boqapi lefapheng la catalysis. Bo-rasaense le baenjiniere ba ntse ba tsoela pele ho hlahloba mekhoa e mecha ea ho kopanya le mekhoa ea ho fetola ho ntlafatsa thepa ea bohlokoa ea li-zeolite tsena, ka sepheo sa ho ntlafatsa ts'ebetso ea bona le ho atolosa lits'ebetso tsa bona indastering ea petrochemical.
Qetellong, li-zeolite tsa ZSM le ZSM23 li bapala karolo ea bohlokoa indastering ea petrochemical, e sebetsa e le lisebelisoa tse feto-fetohang le tse sebetsang hantle bakeng sa lits'ebetso tse fapaneng tsa lik'hemik'hale. Thepa ea bona e ikhethang, ho kenyelletsa le acidity e phahameng, khetho ea sebopeho, le botsitso ba mocheso, li etsa hore e be tsa bohlokoa haholo ho phatloheng ha catalytic, isomerization, hydrocracking le tlhahiso ea li-intermediates tsa petrochemical. Ha tlhoko ea mafura le lik'hemik'hale tsa boleng bo holimo e ntse e hola, bohlokoa ba ZSM le ZSM23 zeolite ho tsamaisa katleho le ts'ebetso ea ts'ebetso ea petrochemical bo ke ke ba feteletsoa.
