发明名称 PRODUCTION OF CATALYTIC BODY FOR CLEANING UP OF WASTE GAS
摘要 PURPOSE:To simultaneously clean up CO and NO2 in a waste gas at 300-900 deg.C by melting and uniting a catalyst component down to 100mum depth from the surface of a carrier contg. a lanthanide oxide thereby depositing said component on the carrier. CONSTITUTION:The catalyst mixture composed of platinum or palladium and lanthanide oxide is deposited on the carrier such as honeycomb type porous ceramic carrier molded of calcium aluminate, silicon dioxide, titanium dioxide, etc. down to about 100mum depth from the surface thereof. The carrier is then subjected to a heat treatment in a 300-1,100 deg.C temp. range by which the catalyst melted and united with the carrier and deposited catalyst for cleaning up of the waste gas is produced. The harmful materials in the waste gas are efficiently cleaned up by installing such catalyst into the waste gas flow passage of a combustion apparatus.
