Abstract

Steam reforming of methane has been carried out aimed at the development of new and highly active catalysts for H2 production. The catalytic properties of Ni catalysts supported on various supports have been investigated in connection with characterization results obtained from XRD, H2 chemisorption, TPR and CO2-TPD. Among the catalysts examined, Ni/Ce-ZrO2 exhibited the best activity and stability. The remarkable catalytic performance is interpreted as a combined result of high oxygen storage capacity of ceria in Ce-ZrO2, strong interaction between Ni and Ce-ZrO2, basic property of the catalyst and rather high capability of H2 uptake.
