ZSM-5 mhando zeolite, ndeve high-silica zeolite uye kuva Si / Al reshiyo anosvika 1000 uye kumusoro, inoratidzawo kuti hydrophobic noruzhinji. The maumbirwo chinoratidza munhu zeolite akadaro kuti hunyambiri uye zvido zvevanhu zvikamu zviri crystalline alum inosilicate anoumbwa 10-membered gwara. The chikuru mamiriro rinoumbwa sere 5-membered zvindori, ine migero chete uye pasina keji isina in. ZSM-5 ane nemhando mbiri muchinjikwa migero, rimwe riri ellipse, uye hwindo dhayamita yayo 0.55 kuti 0.60nm. Sezvo kuita nzvimbo rakafanana Maumbirwe kuwana, kuti zeolite une chimiro kusarudzwa maturo kuti reactants uye zvigadzirwa. Uyezve, ZSM-5 zvakanaka mbishi zvinhu kuti tiwedzere zvokusarudza nokuda rinopindirana marongerwo uye hydrothermal isimbe.
ZSM-5 mhando zeolite zvinowanzodavirwa kureva petrochemical kubudiswa Mazinga, kureva fluidifying, catalyzing uye cracking walnut muitiro somunhu mubatsiri hwokubereka vamwe propylene uye liquefied gasi, uye kuvandudza octane nhamba peturu. Mukuwedzera, zeolite zvinogona kushandiswa pakugadzira ethylbenzene, xylene, phenol, pyridine, etc.
Application:
1.ZSM - 5 samolecular nomusero inoshandiswa FCC tiwedzere: kwakajairika SiO2 / Al2O3 reshiyo riri pakati 40 kusvika 50.
2.ZSM - 5 samolecular nomusero inoshandiswa FCC peturu yokuvirisa kuderedza olefin: kwakajairika SiO2 / Al2O3 reshiyo iri pakati 38 kuti 40.
3.ZSM - 5 samolecular nomusero yaishandiswa resid CATALYTIC Cracking: kwakajairika SiO2 / Al2O3 reshiyo riri pakati 25 kusvika 30.
4.ZSM - 5 samolecular sieves kwemakemikari indasitiri, nemicheka makemikari indasitiri iri zvinowanzoshandiswa chimiro-anyatsosarudza catalysis, akadai diethylbenzene anowedzera, xylene isomerization anowedzera, ethyl acetate, ethylene glycol, ethylene glycol butyl Eteri kuti tiwedzere ane siyana rinoshandiswa.
