Sehlahisoa sa oxidation
E le mohloli oa pele oa li-catalyst, Pt le Pd oxidation catalysts li sebelisoa linaheng tse ling.Leha ho le joalo, li-catalysts tse joalo li ka laola feela tlhahiso ea carbon monoxide le hydrocarbons, kahoo li bitsoa / two way zero catalysts.Ho tloha lilemong tsa bo-1980, 'muso oa' muso oa United States o phahamisitse boemo ba mocheso oa NOX bakeng sa likoloi, e le hore li-catalysts tse joalo li se ke tsa finyella maemo 'me li felisoa butle-butle.
Three way catalyst
Mokhahlelo oa I
Ha maemo a tlhahiso ea NOX a ntlafalitsoe, li-catalyst tsa Pt le Rh li hlahile joalo ka ha linako li hloka.Sehlahisoa sena se ka hloekisa ka nako e le 'ngoe carbon monoxide, hydrocarbon le oxides ea nitrogen, kahoo se bitsoa three-way zero catalyst This is the research of/thre-way 0 catalyst.Leha ho le joalo, ts'ebetso ena e hloka palo e kholo ea lirafshoa tsa bohlokoa tse kang Pt le Rh;E turu ebile e na le chefo ea loto habonolo.Ka hona, ha e loketse likoloi tse sebelisang peterole e nang le loto.
Mokhahlelo oa II:
Pt le Rh li nkeloa sebaka ke Pd ho fokotsa litšenyehelo tsa catalyst.Lokisetsa/tsela tse tharo 0 catalyst le Pt, Rh, Pd e le 'mele o ka sehloohong.E ka hloekisa CO, HC le NO ka nako e le 'ngoe.Melemo ea eona ke ts'ebetso e phahameng, phello e ntle ea tlhoekiso, bophelo bo bolelele, empa litšenyehelo tse phahameng.E sebelisoa haholo linaheng tse ling;
Mokhahlelo oa boraro:
Lisebelisoa tsohle tsa palladium.Mohlala oa lisebelisoa o na le melemo ea ho hloekisa ka nako e le 'ngoe ea CO, HC le NOX, theko e tlaase, botsitso ba mocheso o phahameng oa mocheso le litšobotsi tse timang ka potlako.
Ke feela ka ho laola ka nepo karolelano ea mafura a moea ka har'a fensetere e moqotetsane (ka kakaretso 14.7 ± 0.25) haufi le karo-karolelano ea theoretical air-fuel moo litšila tse tharo li ka hloekisoang ka nako e le 'ngoe.
