This work investigates the production of syngas from butane by rhodium doped ceria/zirconia nanoparticles. The main issue of this study is to improve the catalytic performance at intermediate temperatures of 550 C. In the range of 500 to 600 C, a packed bed reactor with catalyst nanoparticles of 2.0 wt% Rh loading and silica-based plugs achieves nearly complete butane conversion with a hydrogen yield of 77%. In a next step, the production of syngas from butane is investigated by using a disk-shaped packed bed reactor containing Rh/ceria/zirconia nanoparticles at 550 C. Disk-shaped reactors...
