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.
