Vacuum Thermal Treated Ni-CeO(2)/SBA-15 Catalyst for CO(2) Methanation

Ni-CeO(2)/SBA-15-V catalyst was prepared by the impregnation method with vacuum thermal treatment and used for CO(2) methanation reaction. Compared with Ni-CeO(2)/SBA-15-air catalyst with thermal treatment in air, the reduced Ni-CeO(2)/SBA-15-V catalyst with vacuum thermal treatment exhibited higher...

Descripción
Sumario:Ni-CeO(2)/SBA-15-V catalyst was prepared by the impregnation method with vacuum thermal treatment and used for CO(2) methanation reaction. Compared with Ni-CeO(2)/SBA-15-air catalyst with thermal treatment in air, the reduced Ni-CeO(2)/SBA-15-V catalyst with vacuum thermal treatment exhibited higher Ni dispersion and smaller Ni particle size. In CO(2) methanation reaction, the Ni-CeO(2)/SBA-15-V catalyst was more active and selective than the Ni-CeO(2)/SBA-15-air catalyst. The good activity and selectivity of Ni-CeO(2)/SBA-15-V catalyst should be due to highly dispersed Ni in contact with small CeO(2) particles.
