Abstract
CoNi/Al2O3 and MgCoNi/Al2O3 catalysts have been investigated for hydrogen production from CO2 reforming of CH4 reaction at the gas hourly space velocity of 40,000 h？1. The MgO promoted CoNi/Al2O3 catalyst showed much higher conversions (97％ for CO2 and 95％ for CH4) than the CoNi/Al2O3 catalyst. In addition, the stability was maintained for 200 h in CO2 reforming of CH4. The outstanding catalytic activity and stability of the MgO promoted CoNi/Al2O3 catalyst is mainly due to the basic nature of MgO and an intimate interaction between Ni and the support, resulting in preventing coke formation in CO2 reforming of CH4.
