Abstract Cordierite granule with higher surface has been obtained by boiled in oxalic acid.The effect of treatment time on the carrier loss,the mechanical intensity and the surface area was analyzed.CuO-CeO_2 was coated on the cordierite carrier by soaking.Gas chromatography was used to test the catalytic property of CuO-CeO_2/cord catalyst.Results showed when 15%(weight ratio)CuO-CeO_2 was coated on the cordierite,treated 2 h in oxalic acid,the CuO-CeO_2/cord catalyst exhibited a better catalytic activity and selectivity for CO selective oxidation in H_2-rich streams.
