For the production of hydrogen-rich syngas, steam reforming of propane (SRP) has been widely investigated due to its easy-liquefying nature with a higher capacity for hydrogen production per a unit volume than that of methane. The supported Ni-based reforming catalysts are preferred in industrial applications due to their low cost, however, the thermal instability and severe coke depositions generally accelerated a significant deactivation of Ni-based catalysts. To overcome those limitations in the present study, the metal-support interaction between Ni nanoparticles and cobalt-embedded Al2O3 support was found to effectively suppress the deactivation at an optimal amount of cobalt promoter in the CoAl mixed oxide support. |
