在短接触时间下，研究了铑浸渍泡沫氧化铝催化剂上丙烷的部分氧化（POX）和氧化蒸汽重整（OSR）反应。实验在接近大气压的宽温度范围（300-1000°C）内进行。发现700°C的炉温对于该系统中两种反应（POX和OSR）的氢气生产是最佳的。总流量的变化揭示了停留时间对POX和OSR过程中产物分布的影响。氢气的产生几乎不受停留时间的影响，但观察到停留时间对所有其他产物的选择性的影响。烃类副产物在较短的停留时间越来越多地形成，而部分和完全氧化产物的形成随着停留时间的延长而增加。Rh泡沫催化剂在强氧化条件下也显示出有希望的稳定性。
Partial oxidation (POX) and oxidative steam reforming (OSR) of propane have been studied over Rh-impregnated alumina foams in the short contact time regime. The experiments were performed over a wide temperature range (300–1000°C) at close to atmospheric pressure. It was found that a furnace temperature of 700°C is optimal for the production of hydrogen for both reactions (POX and OSR) in this system. Variations in the total flow rate revealed an effect of residence time on the product distribution during both POX and OSR. The production of hydrogen was hardly affected by the residence time, but an influence of the residence time on the selectivity to all other products was observed. Hydrocarbon byproducts were increasingly formed at shorter residence times while formation of partial and complete oxidation products increased with longer residence times. The Rh foam catalyst also showed promising stability under strong oxidation conditions.
