Ukusetyenziswa kwesefo yemolekyuli ye-ZSM njenge-isomerization catalyst
I-ZSM ye-molecular sieve luhlobo lwe-crystalline silicaluminate enobukhulu obukhethekileyo bepore kunye nemilo, esetyenziswe ngokubanzi kwiindlela ezahlukeneyo zeekhemikhali ngenxa yokusebenza kwayo okuhle kakhulu. Phakathi kwabo, ukusetyenziswa kwe-ZSM ye-molecular sieve kwintsimi ye-isomerization catalyst ine-attra...Funda ngokugqithisileyo -
Ubumuncu obuphezulu be-ZSM ye-molecular sieve
I-acidity engaphezulu ye-ZSM ye-molecular sieve yenye yeempawu zayo ezibalulekileyo njenge-catalyst. Le asidi ivela kwiiathom ze-aluminiyam kwi-molecular sieve skeleton, enokubonelela ngeeprotons ukwenza umphezulu weprotonated. Lo mphezulu weprotonated unokuthatha inxaxheba kwiintlobo ezahlukeneyo ze-chemical reaction...Funda ngokugqithisileyo -
Impembelelo ye-Si-Al ratio kwi-ZSM ye-molecular sieve
I-Si / Al ratio (i-Si / Al ratio) yipropati ebalulekileyo ye-ZSM ye-molecular sieve, ebonisa umxholo ohambelanayo we-Si no-Al kwi-molecular sieve. Lo mlinganiselo unempembelelo ebalulekileyo kumsebenzi kunye nokukhetha kwe-ZSM ye-molecular sieve. Okokuqala, umlinganiselo weSi/Al unokuchaphazela ubumuncu be-ZSM m...Funda ngokugqithisileyo -
Isefu yemolekyuli ye-ZSM
I-ZSM i-molecular sieve luhlobo lwe-catalyst enesakhiwo esikhethekileyo, esibonisa ukusebenza kakuhle kwiimpendulo ezininzi zeekhemikhali ngenxa yomsebenzi wayo obalaseleyo we-asidi. Oku kulandelayo zezinye ii-catalysts kunye nee-reactions ezinokuthi zisetyenziselwe izisefu ze-molecular ye-ZSM: 1. I-Isomerization reaction: i-ZSM molecular si...Funda ngokugqithisileyo -
Uphando malunga nomda wokusetyenziswa kwe-silica gel desiccant
Kwimveliso kunye nobomi, i-silica gel ingasetyenziselwa ukomisa i-N2, umoya, i-hydrogen, igesi yendalo [1] njalo njalo. Ngokutsho kwe-asidi kunye ne-alkali, i-desiccant inokwahlulwa ibe yi-acid desiccant, i-alkaline desiccant kunye ne-desiccant engathathi hlangothi [2]. Ijeli ye-silica ibonakala iyinto eyomileyo engathathi hlangothi ebonakala yomile i-NH3, i-HCl, i-SO2, ...Funda ngokugqithisileyo -
Uyenza njani ijeli yesilica?
Ijeli ye-silica luhlobo lwemathiriyeli ye-adsorption esebenzayo kakhulu. Yinto e-amorphous kunye ne-chemical formula yayo yi-mSiO2.nH2O. Idibana nomgangatho weekhemikhali zaseTshayina HG/T2765-2005. Yimpahla eluhlaza ye-desiccant evunywe yi-FDA enokuthi idibane ngqo nokutya kunye neziyobisi. Ijeli yesilika ine...Funda ngokugqithisileyo -
