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 zokhudzana ndi 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 -
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 -
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 -
Momwe mungapangire gel osakaniza silika?
Gelisi ya silika ndi mtundu wa zinthu zomwe zimagwira ntchito kwambiri. Ndi chinthu cha amorphous ndipo mankhwala ake ndi mSiO2.nH2O. Imakumana ndi mankhwala aku China HG/T2765-2005. Ndi zopangira za desiccant zovomerezeka ndi FDA zomwe zimatha kulumikizana mwachindunji ndi chakudya ndi mankhwala. Gel ya silika ili ndi ...Werengani zambiri -
