Zéolite catalyseur

Henan Sinmat Chemical Co., Ltd. bokk na ci defarkat yi gëna wóor ak jaaykatu zeolite bis-60 ci Chine. Ak jaar-jaar yu bari, nu ngi lay dalal bu baax nga jënd zeolite catalyst day-60 bu baax ngir jaay ci sunu usine. Jokkoo leen ak nun ngir am misaal buy maye.

Catalyseur zeolite DAY60 benn xeetu tamis moleculaire la bu am ammonium déaluminé Y{2}type (DAY), am ratio silice bu yéeg ba 60. melni poudre bu weex.

Buñu ko méngale ak zeolite DAY{4}}30, zeolite DAY{5}}60 moo gëna néew aluminium, kaadar bi gëna dëgër, ba noppi gëna am ekilibre ci diggante asidite ak stabilite hydrothermal. DAY-60 zeolite catalyst amna ratio silice-à-alumine bu yéeg, loolu moo jur centre asid yu néew ak doole asid bu yam. Waaye, kaadaram bu xóot bi dealuminated moo gëna dëgër, moo tax dafay wane résistance hydrothermal bu gëna am doole ak mëna dëkku ci anam yu FCC di defaraat (ci kaw 700 degre).

Rax ci dolli, jëmmal macroporous bu DAY{4}}60 katalis zeolit ​​mën na nekk itam ngir reaction molecule yu mag ci xar-xar diwu diis. Ak structure pore bi gëna baax, di forme mesopore yu ci topp, lu mëna yokk njariñu diffusion bi. DAY-60 ci yoon sax ab katalisatëru zeolite USY bu bari silisium la buñu defal pajum dealumination ak dakkal.

DAY-60 zeolite mooy catalyst FCC bi gëna mag, ñu koy njëkka jëfandikoo ci cracking catalytic fluid ngir gëna baaxal produit essence, produit olefin bu woyof, ak baña yàqu ci wen. Yenn saa mu ngi nekk luy jàppale asid ci hydrocracking, muy joxe kàttan ngir xar. Ci wàllu petrochimie, DAY-60 amna ay njariñ yu am solo, lu ci melni soppi diwu diis ak yeesal gasoil.
