Henan Sinmat Chemical Co., Ltd. ndi imodzi mwa opanga odalirika komanso ogulitsa zeolite catalyst h-zsm-5 ku China. Podziwa zambiri, tikukulandirani ndi manja awiri kuti mugule zeolite chothandizira h-zsm-5 zapamwamba zogulitsa kuno kuchokera kufakitale yathu. Lumikizanani nafe zitsanzo zaulere.
Mawu Oyamba
Zeolite H-ZSM-5 chothandizira ndi proton-mtundu (H-type) molecular sieve ya ZSM-5, ilinso ndi dongosolo la MFI. The AlO4-mayunitsi mu H-ZSM-5 chimango ndi H+zolipiritsa, motero amapanga Brønsted acid centers (Si-OH-Al) mkati mwa latisi, komwe ndi komwe kumachititsa chidwi chake. Pafupifupi ma asidi onse{3}}amadalira pa H-ZSM-5 zeolite.
H-ZSM-5 ili ndi mawonekedwe a MFI a mesoporous, motero amawonetsa kusankhika kwapamwamba kwambiri; matanelo ake olumikizidwa-am'mbali mwake amathandizira kufalikira koyenera kwa ma reactants. Gwero la asidi la H-ZSM-5 makamaka ndi Brønsted acid, yomwe imakhala ndi mphamvu zambiri zothandizira; ndipo yachiwiri ndi Lewis acid, yomwe imalimbikitsa machitidwe othandizira.
ZSM-5 ili ndi kukhazikika kwamphamvu kwa hydrothermal komanso kukana kolimba kwa carbon buildup, zomwe zimayamikiridwa kwambiri m'mafakitale.
