Nto acidity ntawm ZSM molecular sieve

Qhov saum npoo acidity ntawm ZSM molecular sieve yog ib qho ntawm nws cov khoom tseem ceeb raws li lub catalyst.
Cov kua qaub no los ntawm cov txhuas atoms hauv cov pob txha molecular sieve, uas tuaj yeem muab cov protons los ua ib qho chaw protonated.
Qhov no protonated nto tuaj yeem koom nrog ntau yam tshuaj tiv thaiv, suav nrog alkylation, acylation, thiab lub cev qhuav dej. Cov av acidity ntawm ZSM molecular sieve tuaj yeem tswj tau.
Cov av acidity ntawm molecular sieve tuaj yeem tswj tau los ntawm kev kho cov txheej txheem synthesis, xws li Si-

Al ratio, synthesis kub, hom template tus neeg sawv cev, thiab lwm yam. Tsis tas li ntawd, qhov saum npoo acidity ntawm molecular sieve kuj tuaj yeem hloov tau los ntawm kev kho tom qab, xws li ion txauv lossis kev kho oxidation.
Qhov saum npoo acidity ntawm ZSM molecular sieve muaj qhov cuam tshuam tseem ceeb ntawm nws txoj haujlwm thiab kev xaiv raws li lub zog catalyst. Ntawm qhov tod tes, deg acidity tuaj yeem txhawb kev ua kom lub substrate, yog li ua kom nrawm cov tshuaj tiv thaiv.
Ntawm qhov tod tes, deg acidity kuj tuaj yeem cuam tshuam cov khoom faib khoom thiab cov tshuaj tiv thaiv kab mob. Piv txwv li, hauv cov tshuaj tiv thaiv alkylation, molecular sieves nrog siab acidity tuaj yeem muab kev xaiv zoo dua alkylation.
Nyob rau hauv luv luv, nto acidity ntawm ZSM molecular sieve yog ib qho ntawm nws cov khoom tseem ceeb raws li ib tug catalyst.
Los ntawm kev nkag siab thiab tswj cov acidity no, nws muaj peev xwm ua kom zoo dua qhov kev ua tau zoo ntawm molecular sieves hauv ntau yam tshuaj tiv thaiv.
