Mayendedwe a chitukuko cha aluminiyamu adamulowetsa
Pachitukuko chatsopano chosangalatsa, ofufuza atsegula bwino aluminiyamu, ndikutsegula mwayi wogwiritsa ntchito m'mafakitale osiyanasiyana.Kupambanaku, komwe kunachitika mu kafukufuku waposachedwa wofalitsidwa mu nyuzipepala ya Nature, kungathe kusintha momwe aluminiyamu amagwiritsidwira ntchito mu ...Werengani zambiri -
Kugwiritsa ntchito ZSM molecular sieve monga isomerization chothandizira
ZSM molecular sieve ndi mtundu wa silicaluminate wa crystalline wokhala ndi kukula kwake ndi mawonekedwe a pore, omwe amagwiritsidwa ntchito kwambiri pamachitidwe osiyanasiyana amankhwala chifukwa cha magwiridwe ake abwino kwambiri.Mwa iwo, kugwiritsa ntchito ZSM molecular sieve m'munda wa isomerization chothandizira ali attra ...Werengani zambiri -
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 okhala ndi protonated awa amatha kutenga nawo gawo mumitundu yosiyanasiyana yamankhwala ...Werengani zambiri -
Zotsatira za chiŵerengero cha Si-Al pa ZSM molecular sieve
Chiŵerengero cha Si / Al (Si / Al chiŵerengero) ndi chinthu chofunika kwambiri cha ZSM molecular sieve, yomwe imasonyeza zomwe zili mu Si ndi Al mu sieve ya maselo.Chiŵerengero ichi chimakhala ndi zotsatira zofunikira pa ntchito ndi kusankha kwa ZSM molecular sieve.Choyamba, chiŵerengero cha Si/Al chingakhudze acidity ya ZSM m ...Werengani zambiri -
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 kuwongolera 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 -
Kugwiritsa ntchito ndi kaphatikizidwe wa ZSM-5 molecular sieve
I. Mau oyamba ZSM-5 molecular sieve ndi mtundu wa zinthu zazing'ono zomwe zimakhala ndi mawonekedwe apadera, zomwe zakhala zikugwiritsidwa ntchito kwambiri m'magawo ambiri chifukwa cha zabwino zake zotsatsa, kukhazikika komanso ntchito yothandiza.Papepalali, kugwiritsa ntchito ndi kaphatikizidwe ka sieve ya molekyulu ya ZSM-5 kudzakhala intr ...Werengani zambiri -
Kafukufuku pa kukula kwa silika gel desiccant
Pakupanga ndi moyo, gel osakaniza a silika angagwiritsidwe ntchito kuumitsa N2, mpweya, haidrojeni, gasi wachilengedwe [1] ndi zina zotero.Malinga ndi asidi ndi alkali, desiccant ikhoza kugawidwa kukhala: acid desiccant, alkaline desiccant ndi neutral desiccant [2].Gelisi ya silika ikuwoneka ngati yowumitsira osalowererapo yomwe imawoneka kuti imawuma NH3, HCl, SO2, ...Werengani zambiri
