I-Three way catalyst

Isigaba I

Njengoba izinga lokukhishwa kwe-NOX selithuthukisiwe, i-Pt ne-Rh catalysts iye yavela njengoba izikhathi zidinga.Le catalyst ingahlanza kanyekanye i-carbon monoxide, ama-hydrocarbon nama-oxides e-nitrogen, ngakho-ke ibizwa ngokuthi i-three way zero catalyst Lolu ucwaningo lwe-/indlela ezintathu 0 catalyst.Nokho, le catalyst idinga inani elikhulu lezinsimbi eziyigugu ezifana ne-Pt ne-Rh;Iyabiza futhi ijwayele ukungenwa ushevu womthofu.Ngakho-ke, azifanele izimoto ezisebenzisa uphethiloli onomthofu.

Isigaba II:

I-Pt ne-Rh ithathelwa indawo yi-Pd ukuze kwehliswe izindleko ze-catalyst.Lungiselela/izindlela ezintathu 0 catalyst nge-Pt, Rh, Pd njengomzimba oyinhloko.Ingakwazi ukuhlanza i-CO, i-HC ne-CHA ngesikhathi esifanayo.Izinzuzo zayo ziwumsebenzi ophezulu, umphumela omuhle wokuhlanzwa, impilo ende, kodwa izindleko eziphezulu.Isetshenziswa kabanzi emazweni angaphandle;

Isigaba sesithathu:

Zonke i-palladium catalyst.Imodeli yokusetshenziswa inezinzuzo zokuhlanzwa ngesikhathi esisodwa kwe-CO, i-HC ne-NOX, izindleko eziphansi, ukuzinza kokushisa okuphezulu kanye nezici zokuvala ukukhanya okusheshayo.

Kuphela ngokulawula ngokunembile isilinganiso sikaphethiloli womoya ngaphakathi kwefasitela elincane (ngokuvamile 14.7 ± 0.25) eduze nenani lethiyori likaphethiloli womoya lapho izinto ezintathu ezingcolisayo zingahlanzwa ngesikhathi esisodwa.
