Pamwamba acidity wa ZSM molecular sieve

Pamwamba acidity wa ZSM maselo sieve ndi chimodzi mwa zinthu zake zofunika monga chothandizira.
Acidity iyi imachokera ku maatomu a aluminiyamu mu chigoba cha molecular sieve, chomwe chingapereke ma protoni kuti apange pamwamba pa protonated.
Malo opangidwa ndi protonated awa amatha kutenga nawo mbali pamachitidwe osiyanasiyana amankhwala, kuphatikiza alkylation, acylation, ndi kutaya madzi m'thupi. Pamwamba acidity wa ZSM maselo sieve akhoza kulamulidwa.
Kuchuluka kwa acidity kwa sieve ya maselo kumatha kuwongoleredwa posintha momwe kaphatikizidwe, monga Si-

Al chiŵerengero, kaphatikizidwe kutentha, mtundu wa template wothandizila, etc. Komanso, asidi padziko sieve maselo akhoza kusinthidwa pambuyo mankhwala, monga kuwombola ion kapena makutidwe ndi okosijeni mankhwala.
Pamwamba acidity wa ZSM maselo sieve ali ndi yofunika kwambiri pa ntchito yake ndi selectivity monga chothandizira. Kumbali imodzi, acidity yapamwamba imatha kulimbikitsa kuyambitsa kwa gawo lapansi, motero kumathandizira kuchuluka kwa zomwe zimachitika.
Kumbali inayi, acidity yapamwamba imathanso kukhudza kugawa kwazinthu komanso njira zomwe zimachitikira. Mwachitsanzo, muzochita za alkylation, ma sieve a molekyulu okhala ndi acidity yapamwamba amatha kupereka kusankha bwino kwa alkylation.
Mwachidule, acidity pamwamba pa ZSM maselo sieve ndi chimodzi mwa zinthu zake zofunika monga chothandizira.
Pomvetsetsa ndi kuwongolera acidity iyi, ndizotheka kukhathamiritsa magwiridwe antchito a ma cell a sieve mumitundu yosiyanasiyana yamankhwala.
