METHOD OF PREPARING SUPPORTED CATALYSTS Russian patent published in 2006 - IPC B01J37/00 B01J23/89 B01J23/74 B01J23/72 

FIELD: gas-treatment catalysts.

SUBSTANCE: supported catalysts are prepared via process of self-propagating thermal synthesis of active component from precursors, which are oxidants and reducers interacting under thermal synthesis conditions and being either in different compounds or combined in the same compound, after which both oxidant and reducer are applied onto support from their solutions, melts, or suspensions. Process is characterized by self-propagating thermal synthesis is conducted within volume of porous support, which is granulated or block-type γ-Al₂O₃ with specific surface 150-230 m²/g and active component precursors applied thereon. Thus obtained superfine oxide catalyst is appropriate to remove hydrocarbons, carbon oxides, and nitrogen from gas emissions.

EFFECT: developed rapid, moderately power-consuming, and environmentally safe process and increased catalyst activity.
