Catalytic autothermal reforming of propane over the noble metal-doped hydrotalcite-type catalysts

Abstract

This study examined the propane reforming performance of noble metal-doped hydrotalcite-type catalysts in a continuous flow fixed-bed catalytic reactor for autothermal reforming. Hydrotalcite-type catalysts were prepared by co-precipitation and were modified by the addition of noble metals, such as Pt, Pd, and Ru. The noble metal-doped hydrotalcite-type catalysts showed better propane reforming performances than the Ni/MgAl catalyst due to the more abundant distribution of Ni catalyst particles and the lower level of carbon deposition. In the case of the hydrotalcite-type catalyst prepared using a mixed solvent of water and alcohol, the reforming activity increased due to an increase in the degree of dispersion and better thermal stability. Propane autothermal reforming over the noble metal-doped hydrotalcite-type catalysts showed higher reforming performance, better stability and less carbon deposition, which highlights their feasibility for hydrogen production from hydrocarbons.
