CATALYST FOR REMOVAL OF CARBON MONOXIDE

摘要

PURPOSE:To enhance the carbon monoxide removal activity of a platinum catalyst and to prolong the life thereof, by preliminarily contacting the platinum catalyst supported by an alumina carrier with gas containing carbon monoxide. CONSTITUTION:The platinum catalyst supported by an alumina carrier is preliminarily contacted with gas containing carbon monoxide at ambient temp. By this method, the carbon monoxide removal activity of the platinum catalyst is enhanced and the usable time thereof is prolonged.
