ZSM-5 mofuta zeolite, bao e leng bo phahameng silica zeolite le ho ba le Si / Al karo-karolelano ea ho fihlela ho 1000 le ka holimo, e boetse e bontša ho bath hydrophobic. Sebopeho tšobotsi ea jwalo zeolite ke hore likarolo paatsepama le rapaletseng tse bonaletsang alum inosilicate entsoe ka 10-membered le kanaleng. Sebopeho mantlha e entsoe ka robeli masale 5-membered, le nang le metjha e feela le e ntle cavities gorole-ntle ho tefo. ZSM-5 na lihlopha tse peli tsa metjha e sefapano, 'ngoe ea tsona ke ellipse, le fensetere bophara lona ke 0,55 ho 0.60nm. E le sebaka karabelong e tšoanang le sebopeho sa fihlelle, ho zeolite na le sebopeho khetha tshebetso e reactants le lihlahisoa. Ho feta moo, ZSM-5 ke e ntle e tala lintho tse bonahalang tse sethothetsi khetha e loketseng ho lumellanang sebopeho le hydrothermal botsitso.
ZSM-5 mofuta zeolite ho pharaletseng sebelisoa ho liindasteri peterolo sebetsa, sebelisoa ho fluidifying e, catalyzing le ho petsoha thulaganyou e ka le mothusi bakeng sa ho hlahisa propylene eketsehileng le khase liquefied, le ho ntlafatsa octane nomoro ea peterole e. Ho phaella moo, zeolite ka sebelisoa ho hlahisa ethylbenzene, xylene, phenol, pyridine, joalo-joalo
