Dịka onye na-emepụta ihe ọhụrụ na teknụzụ sieve molekul, anyị na-enye ngwọta zeolite dị elu, nke a pụrụ ịhazi maka ojiji dị mkpa na nkewa gas, petrochemicals, mmezi gburugburu ebe obibi, na catalysis.
Ngwaahịa na Ngwa Isi:
Ụdị A (3A, 4A, 5A): Obere pores dị iche iche, mmịpụta dị elu, nkwụsi ike okpomọkụ. Ngwa: Ịkpọ nkụ gas (3A: ethylene/propylene; 4A: gas/friji eke), nkewa alkane (5A), mmepụta oxygen (5A), ihe mgbakwunye ncha (4A).
Usoro 13X:
13X: Mmịpụta dị elu nke H₂O, CO₂, na sulfides. Ngwa: Nhicha ikuku, mmịpụta gas.
LSX: SAR dị ala, N₂ adsorption dị elu. Ngwa: Mmepụta oxygen (PSA/VSA).
K-LSX: Nhọrọ N₂ emelitere. Ngwa: Sistemụ oxygen ahụike/ụlọ ọrụ mmepụta ihe.
Usoro ZSM (ZSM-5, ZSM-22, ZSM-23, ZSM-48): Pores 1D/2D, acidity dị elu, catalysis nke na-ahọrọ ọdịdị. Ngwa: Nchacha FCC, isomerization (mmanụ mmanụ/dizel), ọgwụgwọ VOCs, nhazi olefin, nkwalite biomass.
Zeolites Catalytic dị elu:
Beta (BEA): SAR 10-100, ≥400 m²/g, oghere 3D nke nwere mgbanaka 12. Ngwa: FCC, hydrocracking, nnukwu molekul alkylation/isomerization.
Y (FAU): SAR 5-150, ≥600 m²/g, pores buru ibu nke ukwuu. Ngwa: FCC catalysts, hydrocracking, nhazi mmanụ dị arọ, desulfurization.
Amorphous Silica-Alumina (ASA): Acidity na-abụghị kristal, nke a na-agbanwe agbanwe, ≥300 m²/g. Ngwa: FCC catalyst matrix, nkwado hydrotreating, mmịpụta ihe mkpofu.
Nhazi: Anyị bụ ọkachamara n'ịhazi ihe mkpuchi molekul (nha pore, SAR, mgbanwe ion, acidity) iji melite arụmọrụ maka adsorption, catalysis, ma ọ bụ nkewa, site na R&D ruo na ọkwa ụlọ ọrụ mmepụta ihe. A na-ekwe nkwa ịdị ọcha dị elu, nkwụsi ike, na arụmọrụ dị elu.
Gbasara anyị:Anyị na-akwalite ihe ọhụrụ na teknụzụ sieve molekul maka ọrụ ụlọ ọrụ na-adịgide adịgide ma dị irè. Kpọtụrụ anyị ka ị mee ka usoro gị ka mma site na iji zeolites ahaziri ahazi.
