Tasirin rabon Si-Al akan sieve na kwayoyin ZSM

Rabon Si/Al (rabon Si/Al) muhimmin sifa ne na sieve na kwayoyin ZSM, wanda ke nuna alaƙar da ke tsakanin Si da Al a cikin sieve na kwayoyin. Wannan rabo yana da tasiri mai mahimmanci akan aiki da zaɓin sieve na kwayoyin ZSM.
Da farko, rabon Si/Al zai iya shafar sinadarin sieve na kwayoyin ZSM. Gabaɗaya, mafi girman rabon Si-Al, haka nan yake ƙara yawan sinadarin sieve na kwayoyin. Wannan saboda aluminum zai iya samar da ƙarin cibiyar acid a cikin sieve na kwayoyin, yayin da silicon galibi ke ƙayyade tsari da siffar sieve na kwayoyin.
Saboda haka, ana iya sarrafa sinadarin acidity da kuma aikin catalytic na sieve na kwayoyin halitta ta hanyar daidaita rabon Si-Al. Na biyu, rabon Si/Al kuma zai iya shafar daidaito da juriyar zafi na sieve na kwayoyin halitta na ZSM.
Sifefen ƙwayoyin halitta da aka haɗa a mafi girman rabon Si/Al sau da yawa suna da ingantaccen kwanciyar hankali na zafi da na hydrothermal.
Wannan saboda silicon da ke cikin sieve na kwayoyin halitta na iya samar da ƙarin kwanciyar hankali, juriya ga halayen kamar pyrolysis da hydrolysis na acid. Bugu da ƙari, rabon Si/Al kuma na iya shafar girman rami da siffar sieve na kwayoyin ZSM.
Gabaɗaya, mafi girman rabon Si-Al, ƙaramin girman ramin sieve na kwayoyin halitta, kuma siffar ta fi kusa da da'irar. Wannan saboda aluminum na iya samar da ƙarin wuraren haɗin gwiwa a cikin sieve na kwayoyin halitta, wanda ke sa tsarin lu'ulu'u ya fi ƙanƙanta. A taƙaice, tasirin rabon Si-Al akan sieve na kwayoyin halitta na ZSM yana da fuskoki da yawa.
Ta hanyar daidaita rabon Si-Al, za a iya haɗa sirinji na ƙwayoyin halitta tare da girman rami da siffa ta musamman, ana iya haɗa ingantaccen acidity da kwanciyar hankali, don biyan buƙatun halayen catalytic daban-daban.
