Umthelela kanye nomsebenzi we-ejenti yesifanekiso ekuhlanganisweni kwesisefo se-molecular ye-ZSM
Enqubweni yokuhlanganiswa kwe-sieve yamangqamuzana, i-ejenti yesifanekiso idlala indima ebalulekile. I-ejenti yesifanekiso i-molecule ye-organic engaqondisa ukukhula kwekristalu yesisefo samangqamuzana ngokusebenzisa ukuxhumana kwe-intermolecular futhi inqume isakhiwo sayo sokugcina sekristalu. Okokuqala, i-ejenti yesifanekiso ingathinta...Funda kabanzi -
I-ZSM molecular sieve
I-ZSM molecular sieve iwuhlobo lwe-catalyst enesakhiwo esiyingqayizivele, esibonisa ukusebenza okuhle kakhulu ekuphenduleni kwamakhemikhali amaningi ngenxa yokusebenza kwayo okuhle kakhulu kwe-asidi. Okulandelayo ezinye zezisusa nokusabela okungase kusetshenziselwe izisefo ze-molecular ZSM: 1. I-Isomerization reaction: ZSM molecular si...Funda kabanzi -
Ukusetshenziswa kanye nokuhlanganiswa kwe-ZSM-5 ye-molecular sieve
I. Isingeniso I-ZSM-5 i-molecular sieve iwuhlobo lwe-microporous material enesakhiwo esiyingqayizivele, esiye sasetshenziswa kabanzi emikhakheni eminingi ngenxa yezindawo zayo ezinhle zokukhanga, ukuzinza kanye nomsebenzi wokuvuselela. Kuleli phepha, ukusetshenziswa kanye nokuhlanganiswa kwe-ZSM-5 ye-molecular sieve izofakwa ngaphakathi ...Funda kabanzi -
Ucwaningo ngobubanzi bokusetshenziswa kwe-silica gel desiccant
Ekukhiqizeni nasekuphileni, ijeli ye-silica ingasetshenziswa ukomisa i-N2, umoya, i-hydrogen, igesi yemvelo [1] njalonjalo. Ngokusho kwe-asidi ne-alkali, i-desiccant ingahlukaniswa ibe: i-acid desiccant, i-alkaline desiccant kanye ne-desiccant engathathi hlangothi [2]. Ijeli ye-silica ibonakala ingomisi ongathathi hlangothi obonakala bomisa i-NH3, HCl, SO2, ...Funda kabanzi -
Indlela yokwenza i-silica gel?
Ijeli ye-silica iwuhlobo lwempahla ye-adsorption esebenza kakhulu. Kuyinto e-amorphous futhi ifomula yayo yamakhemikhali ithi mSiO2.nH2O. Ihlangabezana nejwayelekile yamakhemikhali aseShayina i-HG/T2765-2005. Kuyinto ye-desiccant eluhlaza evunywe yi-FDA engathintana ngokuqondile nokudla nezidakamizwa. Ijeli ye-silica ine...Funda kabanzi -
