CATALYST DESIGNED TO REDUCE AMOUNT OF NITROGEN OXIDES IN EXHAUST GASES OF ENGINES COMBUSTING THIN FUEL MIXTURE Russian patent published in 2007 - IPC B01J23/40 B01J21/04 B01J21/10 B01J23/02 B01D53/94 

FIELD: fuel combustion catalysts.

SUBSTANCE: invention provides catalyst containing active aluminum oxide, magnesium oxide, at least one platinum-group precious metal, and also at least one material capable of accumulating nitrogen oxides, said magnesium oxide forming homogenous mixed oxide with aluminum oxide in concentration ranging form about 1 to about 40 wt % based on total weight of mixed oxide. The use of catalyst is also disclosed.

EFFECT: increased heat resistance of catalyst and accelerated conversion of nitrogen oxides.
