文摘
In the last two decades, CO preferential oxidation (CO PROX) and CO selective methanation (CO SMET) are assumed as the most feasible reactions for CO removal from H2-rich reformate for low temperature polymer electrolyte membrane fuel cells (LT PEMFC) feeding applications. Despite the existing advantages and disadvantages, both processes provide CO-cleanup to 10 ppm. This brief review illustrates the results obtained during a systematic study of catalysts, their performances and fundamental principles of the selective CO methanation reaction. The most attention is concentrated on Ru and Ni-containing catalysts and their operation in CO SMET reaction.
