Oxidation catalyst

摘要

Catalyst for selective oxidation of hydrocarbons to carbon monoxide, is new, where the catalyst is a mixed oxide based on cerium, titanium and chromium. Independent claims are included for: (1) a process for exhaust gas purification, comprising oxidizing an oxidizable exhaust gas component using the mixed oxide; (2) preparing the oxidation catalyst for internal combustion engine; and (3) an apparatus comprising a combustion chamber and an exhaust gas pipe or exhaust gas recirculation pipe, which is attached to the combustion chamber, where the catalyst is attached within the apparatus.
