Ukwelashwa kwegesi yokukhipha igesi ephezulu esebenza kahle - iplatinum ne-palladium catalyst

I-Platinum palladium yensimbi eyigugu i-catalyst iyindlela ephumelela kakhulu yokwelapha igesi engcolile, yakhiwe i-Pt ne-Pd nezinye izinsimbi eziyigugu, ngakho inomsebenzi ophezulu kakhulu we-catalytic kanye nokukhetha.Ingakwazi ukuguqula kahle izinto eziyingozi kugesi ephumayo futhi iguqule izinto ezingenabungozi, ngaleyo ndlela yehlise ukukhishwa kwegesi ephumayo futhi ivikele imvelo nempilo yabantu esithembele kuyo.

Izingxenye eziyinhloko ze-platinum kanye ne-palladium catalysts izinsimbi eziyigugu ezifana ne-platinum ne-palladium, futhi ukukhethwa kwalezi zinsimbi eziyigugu kukhethekile kakhulu, kuya ngokuphelele ngesimo sokusetshenziswa kwe-catalyst kanye nezidingo zokusabela kwe-catalytic.Ngokuvamile, isilinganiso sobuningi be-platinum ne-palladium ku-platinum ne-palladium catalysts singu-1: 1 noma 2:1, futhi lesi silinganiso singafinyelela umphumela omuhle kakhulu we-catalytic.Ngaphezu kwalokho, ukusekelwa kwe-platinum palladium catalyst nakho kubaluleke kakhulu, okunomthelela omkhulu ekusebenzeni kwe-catalyst.Izithwali ezivamile i-aluminium oxide, i-silicon oxide, i-yttrium oxide, njll., ehlinzeka nge-substrate ezinzile ye-catalyst futhi iqinisekise umphumela osebenza kahle kakhulu we-catalytic.

Izindlela ezijwayelekile zokulungiselela i-platinum kanye ne-palladium catalysts zifaka ukukhulelwa, imvula ngokubambisana, imvula, ukuxubana ngokomzimba nokunye.Indlela yokukhulelwa iwukugxilisa isithwali esinegethivu (imvamisa i-oxide) esixazululweni esiqukethe i-platinum ne-palladium ion, bese senza uchungechunge lwemisebenzi efana nokomisa nokunciphisa, futhi ekugcineni sithole i-platinum ne-palladium catalyst.Indlela yokunciphisa ukuthi i-negative carrier kanye ne-platinum ne-palladium ion yengezwa ohlelweni lokusabela ndawonye, ​​futhi ama-ion eplatinamu ne-palladium adonswa ndawonye phezu kwesiphathi esinegethivu ukuze enze i-platinum ne-palladium catalyst ngokulawula inani le-pH futhi izinga lokushisa lesixazululo.I-platinum palladium catalyst etholwe yilo ndlela inezici zomsebenzi ophezulu, ukukhetha okuphezulu nokuzinza okuphezulu, okuqinisekisa ukusebenza kahle nokuphepha kokwelashwa kwegesi yemfucuza.

Lapho sisebenzisa izinto ze-platinum ne-palladium zensimbi eyigugu, kufanele sinake izindaba zokuphepha.Okokuqala, kuyadingeka ukugwema izimo eziyingozi ezifana nelangabi elivulekile, izinga lokushisa eliphezulu kanye nogesi omile, okungase kuholele ekuwohlokeni kokusebenza kwe-catalyst ngisho nengozi.Okwesibili, i-catalyst idinga ukuhlolwa futhi ishintshwe njalo ukuze kuqinisekiswe ukusebenza kwayo okuvamile futhi ifinyelele umphumela omuhle kakhulu we-catalytic.
