Abstract:Accelerated deterioration tests for selective CO methanation over Ni/TiO2 catalysts were performed to investigate the catalyst degradation factors. The accelerated deterioration test treated the catalyst in the reaction gas flow at the specified temperature (200, 250 or 300 ) for 24 h. After the accelerated deterioration test, the Ni/TiO2 selectivity in CO methanation was reduced due to the enhancement of an undesirable reverse water-gas shift reaction. Powder X-ray diffraction found no change in the TiO2 stru… Show more
