METHOD OF MAKING ICE EXHAUST GAS CLEANING CATALYST Russian patent published in 2012 - IPC B01J37/02 B01J23/63 B01J23/644 B01J37/08 B01D53/94 

FIELD: process engineering.

SUBSTANCE: invention relates to methods of making catalysts, preferably for ICE exhaust cleaners. Proposed method comprises impregnating inert carrier with the mix of organic solutions of compounds of europium and/or cerium, platinum and/or palladium and bismuth, stripping of organic solution and high-temperature treatment of inert carrier at 820-870°C. Used organic solutions represent extracts of compounds of europium and/or cerium, platinum and/or palladium and bismuth to be mixed in preset ratio that allows for the following content of catalyst in active solid phase: oxides of europium and/or cerium - 96-98 wt %, oxide of platinum and/or palladium - 0.5-2 wt %, and bismuth oxide - 1.5-2 wt %.

EFFECT: higher adhesion between active layer with inert carrier surface, higher efficiency and longer life of catalyst.
