摘要
Abstract
Ceria-alumina composite supports were prepared by co-precipitation, impregnation and deposition-precipitation method, respectively. Co-Mo catalysts supported on the composite supports were evaluated for sulfur-resistant methanation and the appropriate content of CeO2 in the composite support was further studied. All the samples were characterized by nitrogen adsorption, X-ray diffraction (XRD) and hydrogen temperature-programmed reduction (H2-TPR). It was found that addition of CeO2 to A12O3 significantly increased the activity of methanation and 25% CeO2-Al2O3 prepared by deposition-precipitation method had the best sulfur-resistant methanation activity.关键词
