Sefa ya 3A ya molekyulu
Sieve ya molekyulu ya 3A ndi aluminate yachitsulo cha alkali, nthawi zina imatchedwanso sieve ya molekyulu ya 3A zeolite. Dzina la Chingerezi: 3A Sieve ya Molecular Sieve Silica / aluminiyamu chiŵerengero: SiO2/ Al2O3≈2 Kukula kwa pore kogwira ntchito: pafupifupi 3A (1A = 0.1nm) Mfundo yogwirira ntchito ya sieve ya molekyulu imagwirizana kwambiri ndi por...Werengani zambiri -
Chaka chatsopano, AOGE yatsopano
AOGE Chemical, kampani yotsogola yopanga zinthu zotsekemera komanso zonyamula zinthu zotsekemera, ikupitilizabe kulamulira makampaniwa ndi zinthu zawo zapamwamba komanso ntchito yabwino kwambiri kwa makasitomala. Monga wosewera wodziwika bwino mumakampani opanga mankhwala, AOGE Chemical imapereka zinthu zosiyanasiyana kuphatikizapo Activated Alumina, Mole...Werengani zambiri -
Kapangidwe ka alumina yoyendetsedwa
Mu chitukuko chatsopano chosangalatsa, ofufuza agwira bwino ntchito aluminiyamu, ndikutsegula dziko la mwayi wogwiritsidwa ntchito m'mafakitale osiyanasiyana. Kupita patsogolo kumeneku, komwe kunanenedwa mu kafukufuku waposachedwa wofalitsidwa mu magazini ya Nature, kuli ndi kuthekera kosintha momwe aluminiyamu imagwiritsidwira ntchito mu...Werengani zambiri -
Kugwiritsa ntchito sieve ya ZSM molecular ngati chothandizira cha isomerization
ZSM molecular sieve ndi mtundu wa crystalline silicaluminate yokhala ndi kukula ndi mawonekedwe apadera a pore, yomwe yakhala ikugwiritsidwa ntchito kwambiri muzochita zosiyanasiyana zamakemikolo chifukwa cha magwiridwe ake abwino kwambiri othandizira. Pakati pawo, kugwiritsa ntchito ZSM molecular sieve m'munda wa isomerization catalyst kumakopa...Werengani zambiri -
Asidi pamwamba pa sieve ya ZSM molecular
Asidi pamwamba pa sieve ya ZSM molecular ndi imodzi mwa zinthu zofunika kwambiri monga chothandizira. Asidi uyu amachokera ku maatomu a aluminiyamu omwe ali mu chigoba cha sieve ya molecular, chomwe chingapereke ma proton kuti apange pamwamba pa protonated. Malo opangidwa ndi proton amatha kutenga nawo mbali muzochita zosiyanasiyana za mankhwala...Werengani zambiri -
Zotsatira za chiŵerengero cha Si-Al pa sieve ya molekyulu ya ZSM
Chiŵerengero cha Si/Al (chiŵerengero cha Si/Al) ndi chinthu chofunikira kwambiri pa sieve ya molecular ya ZSM, chomwe chimasonyeza kuchuluka kwa Si ndi Al mu sieve ya molecular. Chiŵerengerochi chimakhudza kwambiri ntchito ndi kusankha kwa sieve ya molecular ya ZSM. Choyamba, chiŵerengero cha Si/Al chingakhudze acidity ya ZSM m...Werengani zambiri -
ZSM molecular sieve
ZSM molecular sieve ndi mtundu wa catalyst yokhala ndi kapangidwe kake kapadera, komwe kamasonyeza magwiridwe antchito abwino kwambiri mu zochita zambiri zamakemikolo chifukwa cha ntchito yake yabwino kwambiri ya asidi. Izi ndi zina mwa catalysts ndi zochita zomwe ZSM molecular sieves zingagwiritsidwe ntchito: 1. Isomerization reaction: ZSM molecular si...Werengani zambiri -
Kafukufuku wokhudza momwe silika gel desiccant imagwiritsidwira ntchito
Pakupanga ndi moyo, silica gel ingagwiritsidwe ntchito kuumitsa N2, mpweya, haidrojeni, gasi wachilengedwe [1] ndi zina zotero. Malinga ndi asidi ndi alkali, desiccant ingagawidwe m'magulu awa: acid desiccant, alkaline desiccant ndi neutral desiccant [2]. Silica gel imawoneka ngati chowumitsira chosalowerera chomwe chimawoneka kuti chikuumitsa NH3, HCl, SO2, ...Werengani zambiri
