FCC catalyseur desaluminé Y zeolite: 30 jour, jour 60 et jour 120

DAY-30, DAY-60 ak DAY-120 FCC zeolites Y (DAY) yu dealuminé lañu, muy xeetu zeolite Y bu dëgër lool (USY), ak tamis moleculaire yu serie DAY bokk nañu ci mbir yu am solo yi ci katalis FCC yi ci liggéeyukaay yiy raxas diw ci jamono jii.

Lu tax FCC soxla katalis tamis moleculaire?

FCC mooy Fluid Catalytic Cracking, muy liggéey bu am solo buy soppi katalitik ci liggéeyum raffinage diw. Lu gëna am solo ci FCC mooy soppi fraksioŋ petroleum yu diis yi def ko essence, LPG, propylene, olefine yu woyof, gasoil, ak diwu sikl bu woyof.

Catalyst FCC yi war nañu méngoo ak li ñuy laaj ci asidite bu bari, tànneef bu baax ci forme, stabilite hydrothermal bu bari, baña nangu deactivation, ak def fluidisation bu baax. Y{1}}xeetu zeolite tamis moleculaire bokk na ci core composant yi gëna am solo ci catalyseur FCC modern, ak DAY series tamis moleculaire yi dañuy representé Y{2}}xeetu produit tamis moleculaire ci wàllu FCC.

Luy tamis moleculaire DAY?

DAY mooy Y buñ raxas, DAY tamis moleculaire dafay nuru Y-xeetu zeolite biñ def coppite ci luñu raxas. DAY tamis moleculaire nekkul benn kadre bu moom boppam bu wuute lool ak xeetu zeolite Y, waaye xeetu macceer bu am silica Y bu kawe la, te ñu defaree ko ci dealumination zeolite xeetu Y.

Ci pajum hydrothermal ak chimik, xeetu tamis moleculaire Y mën na dindi yenn ci aluminium bi ci kaadar bi, loolu mooy soppi ratio silica ci alumina, asidite, séddaleb asid ci digg bi, stabilite hydrothermal, structure pore, stabilite thermique, ak tànneef catalytique.

Ak katalis FCC yi deñu soxla stabilite hydrothermal bu gëna kawe. Buñu ko méngale ak xeetu tamis moleculaire Y, tamis moleculaire DAY moo gëna mëna dékku tàngoor wu metti wi ak environmaa hydrothermal yi ci katalis FCC yi.

Màndarga yi am ci tamis moleculaire DAY

DAY bokk na ci xeetu sistemu tamis moleculaire Y-, te kaadar bi amna topologie FAU buñ miin. Microporous bimu am ci ñatti dimension yi dafay may reactant yi ak produit yi ñu mëna tasaaroo ci biir kristal bi.

Dealumination benn la ci pexe yi gëna am solo ngir soppali tamis moleculaire DAY, waaye bokkul ak wàññi li ci aluminium. Ci wàllu katalis FCC, fàww ñu am ekilibre ci diggante asidite bi, yatt poro yi, dayo hydrothermal bi, ak tànneef katalitik bi.

Lu tax zeolite DAY am solo ci katalis FCC?

Niñu ko waxoon, katalis FCC yi deñuy laaj ñu defaraat leen lu bari yoon ci biir tàngoor wu metti ak ci anam yu vapër ndox, zeolite Y (DAY) bu dealuminated dafay wane stabilite hydrothermal bu gëna baax ci xeetu tamis moleculaire Y -. Centre asid yi ci biir kaadar DAY mën nañu jàppale bu baax soppi hydrocarbure yu diis yi ci produit yu gëna woyof, te mën nañu soppi structure microporous bi am ñatti dimension boole ci ay matrix ngir méngale performance diffusion catalyseur bi.

Catalyst FCC yi duñu yam ci xar-xar bi gëna am doole, waaye dañuy laaj ñu saytu liggéeyu xar-xar bi ak tànneefi produit yi. DAY zeolite mën nañu ko saytu ci ay parametre yu melni rasio silice ci alumina, dayo pepp, asidite, ak porose.

Ci anam wu fësoon, katalis FCC du tamis moleculaire bu sell! Sistem la bu boole tamis moleculaire, matrix, liant ak yeneen mbir yu am njariñ. DAY tamis moleculaire benn la ci macceer yi gëna am solo ci katalis FCC, mën nañu ko boole ak matrix katalis, moo gën nekk katalis FCC bi ci boppam.
