Propane is one of prospective feed gases of steam reforming because the propane is main component gas of liquefied petroleum gas (LPG) used widely in household, transport, and other uses. Moreover, propane can generate so much hydrogen per unit volume of feed gas that is used commercially. Catalysts based on Ni/Al2O3 are widely used for steam reforming process but these catalysts can be easily aggregated and deactivated due to carbon deposition. But, using yttrium stabilized zirconium (YSZ) as catalytic supporter can solve these problems because YSZ is thermally stable and expected influence of oxygen vacancies of YSZ In this study, YSZ was used as catalytic supporter in 1 wt% M/30 wt% NiO/YSZ (M= Ru, Rh, Pd, Ag) that was used for propane steam reforming (PSR) to study how YSZ affects performance of PSR. In addition, this study also tried to find out which noble metal is more appropriate to PSR to inhibit carbon deposition. |
