ZSM-5 Taxanaha Qaabka-door Zeolites
ZSM-5 zeolite waxaa loo isticmaali karaa warshadaha petrochemical, warshadaha kiimikada ganaaxa iyo beeraha kale sababtoo ah kanaalka daloolka tooska ah ee saddex-geesoodka ah ee gaarka ah, qaabka gaarka ah ee la xushay, isomerization iyo awoodda aromatization. Hadda, waxaa lagu dabaqi karaa kicinta FCC ama wax lagu daro kuwaas oo hagaajin kara nambarka batroolka octane, kicinta biyaha/aonhydro dewaxing iyo habka unugga isomerization xylene, isu-dheellitirnaanta toluene iyo alkylation. Nambarka gaaska octane waa la wanaajin karaa waxa ku jira olefin sidoo kale waa la kordhin karaa haddii zeolites lagu daro kicinta FCC ee falcelinta FBR-FCC. Shirkaddayada, ZSM-5 serial qaabka-doorashada zeolites waxay leeyihiin saamiga silica-alumina kala duwan, laga bilaabo 25 ilaa 500. Qaybinta qaybinta waxaa lagu hagaajin karaa iyadoo loo eegayo shuruudaha macaamiisha. Awoodda isomerization iyo xasilloonida dhaqdhaqaaqa waa la bedeli karaa marka aysidhka la hagaajiyo iyadoo la beddelayo saamiga silica-alumina sida waafaqsan shuruudahaaga.

| Midabka | Cawlan khafiif ah | |
| Habka Isku-dhafka: Marka la eego heerkulka sare iyo xaaladaha cadaadiska sare, zeolites ZSM-5 waxaa la soo saari doonaa ka dib markii la isku daro hydrothermal crystallization, shaandhaynta, dhaqidda, wax ka beddelka iyo qalajinta adoo isticmaalaya cusbada aluminium iyo silicate sida walxaha ugu muhiimsan. | ||
