| Outline of Final Research Achievements |
In order to avoid a thermal runaway of a catalytic reaction, a catalyst with self-controlling function for the suppression of undesired reaction was investigated. Residual chlorine on alumina-supported nickel catalysts significantly suppressed CO2 methanation and the reverse water gas-shift reaction in the course of selective CO methanation. FT-IR measurements revealed that chlorine suppressed the dissociation of CO2 on the catalyst surface. Also, vanadium was effective for the selectivity control. A mesoporous silica-coated Ni/alumina-based catalyst was developed for the further development of the suppression of the thermal runaway reaction. The catalytic activity and CO removal ability of the Ni/AlVOx catalyst were significantly improved by the coating of mesoporous silica on the Ni/AlVOx. The Ni-V species transported from the Ni/AlVOx to the coating layer may also act as active sites for CO methanation.
