Henan Sinmat Chemical Co., Ltd. waa mid ka mid ah soosaarayaasha iyo alaab-qeybiyeyaasha ugu kalsoonaan karo ee maalinta-60 ee Shiinaha. Iyada oo leh waayo-aragnimo badan, waxaanu si diiran kuugu soo dhawaynaynaa inaad iibsato maalin-60 kiciya zeolite tayo sare leh oo iib ah halkan warshadeena. Nala soo xidhiidh muunad bilaash ah.
Hordhac
Zeolite catalyst DAY -60 waa nooc ka mid ah Ammonium Y-nooca (DAY) shaandho molecular, oo leh silica sare -ila - saamiga alumina ee caadiga ah 60. Waxa kale oo ay haysaa dusha sare ee FAU iyo saddex-cabbir ah macropores (guud ahaan waxa uu u muuqdaa qiyaas ahaan budo) nm0.
Marka la barbar dhigo DAY{4}}30, DAY-60 zeolite waxa uu leeyahay aluminium hoose oo ka kooban, qaab-dhismeed aad u deggan, oo waxa uu ku gaadhaa dheellitir wanaagsan oo u dhexeeya aashitada iyo xasiloonida kuleyliyaha. DAY-60 kicinta zeolite waxay leedahay saamiga silica-to-alumina oo aad u sarreeya, taasoo keentay in xarumaha asiidhku yaraadaan iyo xoogga aashitada dhexdhexaad ah. Si kastaba ha ahaatee, qaab-dhismeedkeeda si qoto dheer loo xalliyo ayaa ah mid deggan, sidaas awgeed waxay muujinaysaa caabbinta biyo-mareenka xooggan iyo awoodda u adkeysiga xaaladaha dib u soo kabashada FCC (ka sarreeya 700 digrii).
Intaa waxa dheer, qaab dhismeedka makroporous ee DAY-60 kiciye zeolite waxa kale oo uu ku haboon yahay falcelinta molecule waaweyn ee dilaaca saliida culus. Iyo qaabdhismeedkeeda la hagaajiyay, qayb ahaan samaynta mesopores sare, taas oo hagaajin karta waxtarka faafinta. DAY-60 asal ahaan waa silica-sare USY zeolite kisiyaha kaas oo maray daawaynta dealuminating iyo xasilinta.
DAY-60 zeolite waa kicinta guud ee FCC, oo ugu horayn loo isticmaalo dildilaaca dareeraha dareeraha ah si loo wanaajiyo wax soo saarka gaaska, dhalidda olefin fudud, iyo iska caabinta wasakhowga birta. Mararka qaarkood, waxay sidoo kale u adeegtaa sidii taageero aashito ah ee hydrocracking, siinta awoodaha dildilaaca. Ka-hortagga qoto-dheer ee batroolka, DAY-60 waxay sidoo kale leedahay codsiyo muhiim ah, sida beddelka saliidda culus iyo cusboonaysiinta naaftada.
