Ukwahlukaniswa Kwama-Precious Metal Catalysts

Ama-Catalyst angahlukaniswa ngokuya ngokuthi ingxenye esebenzayo iyasekelwa yini ekusekelweni:

Ama-Metal Catalysts Angasekelwe:Lawa ama-catalyst ensimbi ngaphandle kokusekelwa. Angaphinde ahlukaniswe abe izinhlobo-zensimbi eyodwa kanye nengxubevange ngokusekelwe ekubunjweni kwazo. Ngokuvamile zisetshenziswa ngendlela yezinsimbi zohlaka, amameshi ensimbi, izimpushana zensimbi, izinhlayiya zensimbi, izinsalela zensimbi, namafilimu ensimbi ahwamukayo.

Ama-Metal Catalyst Asekelwe:Lawa ama-catalyst lapho ingxenye yensimbi isekelwa kusekelo. Lokhu kuthuthukisa ukuhlakazeka nokuzinza kokushisa kwengxenye yensimbi, kunikeza i-catalyst isakhiwo esifanelekile se-pore, ukwakheka, namandla okusebenza. Ama-catalyst ensimbi amaningi asekelwayo alungiswa ngokufaka isixazululo sikasawoti wensimbi esisekelweni, okulandelwa ukuguqulwa kwemvula noma ukubola nokunciphisa okushisayo.

I-Multi-metal Catalysts:Lawa ma-catalyst ahlanganisa izinsimbi ezimbili noma ngaphezulu. Izibonelo zifaka i-platinum-i-rhenium bimetallic (noma{2}}izinto eziningi ze-metallic) eziguqulayo ezisekelwa ku-chlorine{3}}equkethe -i-alumina. Abonisa ukusebenza okuphezulu kakhulu uma kuqhathaniswa neplatinamu eshiwo ngenhla-kuphela ama-catalysts aguqulayo. Kulawa ma-catalyst, izinsimbi eziningi ezisekelwayo zingakha amaqoqo ensimbi kanambambili noma{8}}aningi, athuthukise ngokuphawulekayo ukusakazeka okusebenzayo kwengxenye esebenzayo.
