Experiment on Anti-aging Property and Mechanism of CO Catalytic Materials for Two Kinds of Coal Mine Refuge Chamber

CO catalytic material has been widely used in mine refuge chamber and load type Pd and other active auxiliary catalyst is good catalysts for low-temperature CO oxidation, but mine refuge chamber complex and harsh environmental conditions can influence on the catalytic performance. In this paper, the material properties of the catalyst under the humid and hot, curing, and other environmental conditions were studied; reaction mechanisms concerning the various of catalytic systems are discussed.
