Abstract

The oxidation of carbon monoxide and hydrocarbons, in particular from exhaust gases from internal-combustion engines, by means of oxygen-containing gases to give carbon dioxide and water is carried out at temperatures of from 150 to 800<o>C in the presence of a supported catalyst. The supported catalyst here comprises aluminium oxide which has been partially converted into alpha -Al2O3 as support, to which from 0.2 to 10% by weight of cerium as oxide has been applied as active constituent.
