Abstract

A porous anodic alumina-supported 4.9 wt % nickel catalyst showed deactivation in steam reforming of methane at 700 °C, and this was mainly ascribed to Ni oxidation. The influence of hydrogen additive was examined by adding hydrogen into feed, and no deactivation was found during 20h when hydrogen with H2/H2O = 1/3 was added. The influence of electrical heating over catalyst stability was also examined, and the results showed a stable 93% methane conversion for 30 h. 0.078 wt% Pt-doped 4.9 wt % nickel catalyst showed a stable SRM reactivity even without the prereduction with hydrogen.
