method of preparing CATALYST FOR COMPLETE OXIDATION OF HYDROCARBON, the catalyst prepared by this method AIR CLEANING METHOD AND FROM HYDROCARBON USING CATALYST OBTAINED

摘要

1. A process for the preparation of complete oxidation of hydrocarbons, particularly hydrocarbon impurities in the air of a catalyst to air purification, comprising applying the platinum or palladium on zirconium oxide volframatsoderzhaschy calcined carrier by impregnation with a water solution of a platinum or palladium compound, followed by calcination in air at a temperature of 300-500 ° C and reducing in a hydrogen stream at 300-500 ° C, characterized in that the carrier further volframatsoderzhaschy zirconium oxide modified with gallium ions by their n aneseniya of galliya.2 nitrate aqueous solution. A method according to claim 1, characterized in that the gallium is applied to a zirconium oxide carrier volframatsoderzhaschy platinoy.3 simultaneously. A method according to claim 1, characterized in that the gallium is applied to the carrier volframatsoderzhaschy zirconium oxide prior to the application of platinum, followed by further thermal treatment at a temperature of 300-500 ° C.4. A method according to claim 1, characterized in that as a zirconium oxide carrier is used tsirkoniya.5 hydroxide. A method according to claim 1, characterized in that as a zirconium oxide carrier is used tsirkoniya.6 oxide.
