Abstract:

Catalytic oxidation for the removal of trace amount of carbon monoxide in olefins needs less equipments，gives more manipulability and higher removal efficiency. In this paper，the research progress of catalysts in such process is reviewed. The mechanism for the removal of trace amount of carbon monoxide is introduced. The CO oxidation activities of Cu-based catalyst are compared among three oxidation states，i.e. Cu²⁺，Cu¹⁺ and Cu⁰. The impact of active lattice oxygen properties upon catalytic activities in CO oxidation is discussed in detail，and the research perspective is also presented.
