Fur Xalalka Molecular-ka ee Sare: Zeolites loogu talagalay Heer Sare ee Warshadaha

Annagoo ah hal-abuure hormuud ka ah tignoolajiyada shaandhada molecular-ka, waxaan bixinaa xalal zeolite ah oo waxqabad sare leh oo la beddeli karo oo loogu talagalay codsiyada muhiimka ah ee kala-soocidda gaaska, kiimikooyinka batroolka, hagaajinta deegaanka, iyo katalisyada.

Badeecadaha Muhiimka ah iyo Codsiyada:

Nooca A (3A, 4A, 5A): Micropores isku mid ah, nuugid sare, xasillooni kuleyl. Adeegsiga: Qallajinta gaaska (3A: ethylene/propylene; 4A: gaaska dabiiciga ah/qaboojiyeyaasha), kala soocidda alkane (5A), soo saarista oksijiinta (5A), waxyaabaha lagu daro saabuunta (4A).

Taxanaha 13X:

13X: Neefsasho sare oo H₂O, CO₂, iyo sulfide. Adeegsiga: Nadiifinta hawada, fuuqbaxa gaaska.

LSX: SAR hooseeya, nuugista N₂ oo sareysa. Codsiyada: Soo saarista oksijiinta (PSA/VSA).

K-LSX: Xulasho N₂ oo la xoojiyay. Codsiyada: Nidaamyada oksijiinta caafimaadka/warshadaha.

Taxanaha ZSM (ZSM-5, ZSM-22, ZSM-23, ZSM-48): daloolada 1D/2D, aashitada sare, kicinta qaabka-doorashada. Codsiyada: Sifeynta FCC, isomerization (saliidaynta/naaftada), daaweynta VOCs, habaynta olefin, casriyeynta bayoolajiga.

Zeolites-ka Catalytic-ga ee Horumarsan:

Beta (BEA): SAR 10-100, ≥400 m²/g, daloolada 12-ring ee 3D. Codsiyada: FCC, hydrocracking, alkylation/isomerization molecule-weyn.

Y (FAU): SAR 5-150, ≥600 m²/g, daloolo aad u weyn. Adeegsiga: Katalystayaasha FCC, hydrocracking, farsamaynta saliidda culus, nadiifinta sulfurization.

Amorphous Silica-Alumina (ASA): Aashitada aan kristalin ahayn, ee la hagaajin karo, ≥300 m²/g. Codsiyada: Shaxda kicinta FCC, taageerada daaweynta biyaha, nuugista qashinka.

Habaynta: Waxaan ku takhasusnay habaynta shaandhada molecular-ka (cabirka daloolada, SAR, isweydaarsiga ion-ka, aashitada) si kor loogu qaado waxqabadka nuugista, katalisnimada, ama kala-soocidda, laga bilaabo cilmi-baarista iyo horumarinta ilaa baaxadda warshadaha. Waxaa la damaanad qaaday daahirnimo sare, xasillooni, iyo hufnaan.

Nagu Saabsan:Waxaan ku dadaalnaa hal-abuurka tignoolajiyada shaandhada molecular-ka si loo helo hawlgallo warshadeed oo waara oo hufan. Nala soo xiriir si aad u wanaajiso hababkaaga iyadoo la adeegsanayo zeolites loo habeeyay.
