Tsegulani Mayankho Apamwamba a Molekyulu: Zeolite Zopangidwira Ubwino Wamafakitale

Monga katswiri wotsogola muukadaulo wa sieve ya molecular, timapereka mayankho a zeolite ogwira ntchito bwino komanso osinthika kuti agwiritsidwe ntchito kwambiri pakulekanitsa mpweya, petrochemicals, kukonza zachilengedwe, ndi catalysis.

Zogulitsa ndi Mapulogalamu Ofunika:

Mtundu wa A (3A, 4A, 5A): Ma micropores ofanana, kulowetsedwa kwambiri, kukhazikika kwa kutentha. Ntchito: Kuumitsa mpweya (3A: ethylene/propylene; 4A: mpweya wachilengedwe/mafiriji), kulekanitsa alkane (5A), kupanga mpweya (5A), zowonjezera zotsukira (4A).

Mndandanda wa 13X:

13X: Kuchuluka kwa H₂O, CO₂, sulfide. Ntchito: Kuyeretsa mpweya, kutaya madzi m'thupi ndi mpweya.

LSX: Kutsika kwa SAR, kuchuluka kwa N₂ adsorption. Ntchito: Kupanga okosijeni (PSA/VSA).

K-LSX: Kusankha bwino kwa N₂. Kugwiritsa ntchito: Makina a okosijeni azachipatala/mafakitale.

ZSM-Series (ZSM-5, ZSM-22, ZSM-23, ZSM-48): Ma pores a 1D/2D, acidity yambiri, catalysis yosankha mawonekedwe. Ntchito: Kuyeretsa kwa FCC, isomerization (mafuta odzola/dizilo), chithandizo cha VOCs, kukonza olefin, kukonzanso biomass.

Ma Catalytic Zeolites Apamwamba:

Beta (BEA): SAR 10-100, ≥400 m²/g, 3D 12-ring pores. Ntchito: FCC, hydrocracking, large-molecule alkylation/isomerization.

Y (FAU): SAR 5-150, ≥600 m²/g, ma pores akuluakulu kwambiri. Ntchito: Zothandizira pa FCC, kuphwanya madzi, kukonza mafuta ambiri, kuchotsa sulfurization.

Amorphous Silica-Alumina (ASA): Yosakhala ya kristalo, acidity yosinthika, ≥300 m²/g. Ntchito: FCC catalyst matrix, hydrotreating support, waste adsorption.

Kusintha: Timagwira ntchito yokonza ma molecular seeves (kukula kwa ma pore, SAR, kusinthana kwa ma ion, acidity) kuti tiwonjezere magwiridwe antchito a ma adsorption, catalysis, kapena lekanitsani, kuchokera ku R&D kupita ku mafakitale. Timatsimikizira kuyera kwakukulu, kukhazikika, komanso kugwira ntchito bwino.

Zambiri zaife:Timayendetsa luso lamakono mu ukadaulo wa sieve ya molecular kuti ntchito zamafakitale zikhale zokhazikika komanso zogwira mtima. Lumikizanani nafe kuti mukonze bwino njira zanu ndi ma zeolite opangidwa mwaluso.
