Zotsatira ndi ntchito ya template wothandizira pa synthesis ya ZSM molecular sieve
Popanga kaphatikizidwe ka molecular sieve, wothandizira ma template amagwira ntchito yofunika kwambiri. Wothandizira template ndi molekyulu ya organic yomwe imatha kutsogolera kukula kwa kristalo wa sieve ya maselo kudzera pakulumikizana kwa ma intermolecular ndikuzindikira mawonekedwe ake omaliza a kristalo. Choyamba, wothandizila template akhoza kukhudza ...Werengani zambiri -
ZSM molecular sieve
ZSM molecular sieve ndi mtundu wa chothandizira chokhala ndi mawonekedwe apadera, omwe amawonetsa kuchita bwino pamachitidwe ambiri amankhwala chifukwa cha ntchito yake yabwino ya acidic. Zotsatirazi ndi zina zomwe zimachititsa kuti maselo a ZSM agwiritse ntchito: 1. Isomerization reaction: ZSM molecular sieve ...Werengani zambiri -
