Research on the processing of fuel for the commercialization of fuel cells has focused largely on hydrogen production from hydrocarbons and alcohols, with steam reforming recognized as commercially feasible given its production of hydrogen-rich gas. However it suffers from catalyst deactivation, a problem which has been widely investigated. This work aimed to evaluate the activities of nickel-based catalysts containing potassium titanate and the effects of additives such as potassium. The activities and stabilities of Ni/KTixOy-Al2O3 catalysts were compared with those of a commercial catalyst for methane steam reforming. Nickel-based catalysts containing titanate, Ni/KTixOy-Al2O3, were prepared with a fixed 10 wt.% loading of nickel, and 11 – 50 wt.% loadings of potassium titanates. The nickel-based catalysts were compared with FCR-4 and Ni/Al2O3 for steam reforming activity: they showed competitive performances. |
