Hydrogen Production from Coke Oven Gas by CO2 Reforming over Mesoporous La2O3-ZrO2 Supported Ni Catalyst

The CO2 reforming of coke oven gas (COG) for hydrogen production was investigated over mesoporous NiO/La2O3-ZrO2 catalysts. At optimized reaction conditions, the conversions of CH4 and CO2 more than 93%, while a H2 selectivity of 94.7% and a CO selectivity of 98.6% have been achieved at 800 °C. The effect of reaction temperature on the catalytic performance was investigated in detail. The catalysts with appropriate La2O3 content showed better catalytic activity and resistance to coking, which will be promising catalysts in the catalytic dry reforming of COG.
