Ulwalathiso lophuhliso lwe-alumina esebenzayo
Kuphuhliso olutsha olunomdla, abaphandi baye bavula ngempumelelo i-aluminiyam, evula ihlabathi lamathuba okusetyenziswa kumashishini ahlukeneyo.Impumelelo, echazwe kuphononongo lwakutsha nje olupapashwe kwijenali yeNdalo, inamandla okuguqula indlela esetyenziswa ngayo ialuminiyam...Funda ngokugqithisileyo -
Ukusetyenziswa kwesefo yemolekyuli ye-ZSM njenge-isomerization catalyst
I-ZSM ye-molecular sieve luhlobo lwe-crystalline silicaluminate enobungakanani obukhethekileyo bepore kunye nokumila, esetyenziswe ngokubanzi kwiimpendulo zeekhemikhali ezahlukeneyo 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 -
Isiphumo kunye nomsebenzi we-agent ye-template kwi-synthesis ye-ZSM ye-molecular sieve
Kwinkqubo ye-molecular sieve synthesis, i-agent ye-template idlala indima ebalulekileyo.I-agent ye-template yi-molecule ye-organic engakwazi ukukhokela ukukhula kwe-crystal ye-molecular sieve ngokusebenzisa i-intermolecular interaction kwaye inqume isakhiwo sayo sokugqibela se-crystal.Okokuqala, i-arhente yetemplate inokuchaphazela...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 -
Ukusetyenziswa kunye nokuhlanganiswa kwe-ZSM-5 ye-molecular sieve
I. Intshayelelo ye-ZSM-5 ye-molecular sieve luhlobo lwe-microporous material kunye nesakhiwo esiyingqayizivele, esiye sasetyenziswa ngokubanzi kwiindawo ezininzi ngenxa yeempawu zayo ezintle zokubhengezwa, ukuzinza kunye nomsebenzi we-catalytic.Kweli phepha, ukusetyenziswa kunye nokuhlanganiswa kwe-ZSM-5 ye-molecular sieve iya kuba yintr...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
