Combined H2O and CO2 Reforming of Methane Over Ni-Ce-ZrO2 Catalysts for Gas to Liquids (GTL)

摘要

Ni-Ce-ZrO2 catalysts with various CeO2/ZrO2 ratios have been prepared by co-precipitation method and applied for combined steam and carbon dioxide reforming of methane (CSCRM) to produce synthesis gas (H2/CO = 2) for gas to liquid (GTL) process. 15% Ni-Ce_(0.8)Zr_(0.2)O2 exhibits the highest activity as well as stability in CSCRM due to finely dispersed NiO with intimate contact with support and high oxygen storage capacity.
