Ikoreshwa rya ZSM ya molekile ya sikeri nka catiseri ya isomerisation
Amashanyarazi ya ZSM ni ubwoko bwa silisiyumu ya kristaline ifite ubunini nubunini byihariye bya pore, byakoreshejwe cyane muburyo butandukanye bwimiti kubera imikorere ya catalitiki nziza. Muri byo, ikoreshwa rya molekile ya ZSM murwego rwa catalizator isomerisation ifite attra ...Soma byinshi -
Ubuso bwa acide ya ZSM ya molekile
Ubuso bwa acide ya molekile ya ZSM nimwe mubintu byingenzi nkibikoresho. Iyi acide ituruka kuri atome ya aluminium muri skeleton ya molekile ya sikeli, ishobora gutanga proton kugirango ikore ubuso bwa protonone. Ubuso bwa protonate bushobora kwitabira imiti itandukanye ya reaction ...Soma byinshi -
Ingaruka yikigereranyo cya Si-Al kumashanyarazi ya ZSM
Ikigereranyo cya Si / Al (igipimo cya Si / Al) ni umutungo wingenzi wa ZSM ya molekile ya molekile, igaragaza ibintu ugereranije na Si na Al mubyuma bya molekile. Iri gereranya rifite ingaruka zingenzi kubikorwa no guhitamo amashanyarazi ya ZSM. Ubwa mbere, igipimo cya Si / Al gishobora kugira ingaruka kuri acide ya ZSM m ...Soma byinshi -
ZSM ya molekile
Amashanyarazi ya ZSM ni ubwoko bwa catalizator ifite imiterere yihariye, yerekana imikorere myiza mubikorwa byinshi bya chimique bitewe nibikorwa byayo byiza bya acide. Ibikurikira nimwe mubisubizo hamwe nibisubizo ZSM ya molekile ya sikeri ishobora gukoreshwa kuri: 1. Igisubizo cya Isomerisation: ZSM molecular si ...Soma byinshi -
Ubushakashatsi kurwego rwo gukoresha silika gel desiccant
Mubikorwa nubuzima, silika gel irashobora gukoreshwa mukumisha N2, umwuka, hydrogène, gaze naturel [1] nibindi. Ukurikije aside na alkali, desiccant irashobora kugabanywamo ibice: desiccant acide, desalcant ya alkaline na desiccant idafite aho ibogamiye [2]. Silica gel isa nkaho yumye idafite aho ibogamiye isa nkumye NH3, HCl, SO2, ...Soma byinshi -
