Process for the selective oxidation of cabon monoxide

摘要

A process for the selective oxidation of carbon monoxide in a hydrogen-rich gas stream, wherein a mixture comprising the hydrogen-rich gas stream and a molecular oxygen-containing gas is contacted with a monolithic structure of a material having a thermal conductivity of at least 30 W/m.K, which monolithic structure is provided with a catalyst for the selective oxidation of carbon monoxide, at a gas velocity such that the flow through the monolithic structure is laminar. The invention further relates to a reactor comprising such a monolithic structure, wherein particles of the catalyst are contained in the monolithic structure.
