Fungura ibisubizo bya molekile bigezweho: Zeolite zigenewe ubuhanga mu nganda

Nk'umuvumbuzi ukomeye mu ikoranabuhanga rya molekile, dutanga ibisubizo bya zeolite bikora neza kandi bishobora guhindurwa mu buryo busanzwe, mu bikorwa by'ingenzi mu gutandukanya imyuka, peteroli, gutunganya ibidukikije, no gukata.

Ibicuruzwa by'ingenzi n'ikoreshwa ryabyo:

Ubwoko bwa A (3A, 4A, 5A): Uduce duto tw’imikorobe, ubushobozi bwo kuvogera cyane, ubushyuhe budahindagurika. Imikoreshereze: Kumisha imyuka (3A: ethylene/propylene; 4A: gazi karemano/firigo), gutandukanya alkane (5A), gukora ogisijeni (5A), inyongeramusaruro z’amazi (4A).

Urukurikirane rwa 13X:

13X: Kunyurwa cyane kwa H₂O, CO₂, sulfide. Imikoreshereze: Gusukura umwuka, kubura umwuka.

LSX: SAR iri hasi, N₂ iri hejuru yo kunyuzwa mu mubiri. Imikoreshereze: Gutanga ogisijeni (PSA/VSA).

K-LSX: Uburyo bwo kongera ubushobozi bwo guhitamo N₂. Imikoreshereze: Sisitemu za ogisijeni mu buvuzi/mu nganda.

ZSM-Series (ZSM-5, ZSM-22, ZSM-23, ZSM-48): Uduce twa 1D/2D, aside nyinshi, catalysis ihitamo imiterere. Imikoreshereze: Gutunganya FCC, isomerization (amavuta/amavuta), kuvura VOCs, gutunganya olefin, kongera ingufu za biomass.

Zeolite zigezweho za Catalytic:

Beta (BEA): SAR 10-100, ≥400 m²/g, imyenge ya 3D ifite impeta 12. Imikoreshereze: FCC, gucikamo uduce duto, alkylation/isomerization ya molekuli nini.

Y (FAU): SAR 5-150, ≥600 m²/g, imyenge minini cyane. Imikoreshereze: Katalysts za FCC, gucikamo uduce duto, gutunganya amavuta menshi, gusohora sulfur.

Silika-Alumina idafite ibara ry'umukara (ASA): Idahinduka nk'iry'ubutare, ihinduka nk'iry'ubutare, ≥300 m²/g. Imikoreshereze: FCC catalyst matrix, inkunga yo kuvura amazi, uburyo bwo kunyuza imyanda.

Guhindura: Twibanda ku gutunganya utuyunguruzo twa molekile (ingano y'imyenge, SAR, ihindagurika rya iyoni, aside) kugira ngo twongere imikorere yo kwinjiza, gukata, cyangwa gutandukanya, kuva ku bushakashatsi no guteza imbere ibidukikije kugeza ku rwego rw'inganda. Bizeza ko hari ubuziranenge, ituze n'imikorere myiza.

Ibyerekeye Twe:Dushyira imbere udushya mu ikoranabuhanga rya molekile mu gutunganya ibintu kugira ngo ibikorwa by'inganda bikomeze kandi bigire umusaruro. Twandikire kugira ngo wongere uburyo bwawe bwo gukora ukoresheje zeolite zikozwe mu buryo bwa zeolite.
