Glycerol is produced as a major byproduct in a biodiesel production process but it has been thrown out as a waste. The glycerol byproduct will increase rapidly in amount if the biodiesel commercialization is attainable, so a reforming technology is required for glycerol to be used as a high value product. In the present study, the catalytic activity of several supported catalysts for glycerol-steam reforming was measured. The glycerol conversion of Ni foam-supported catalyst was higher than that of other supported catalysts such as Al₂O₃, monolith, and SBA-15. The Ni foam-supported catalyst had a good thermal dispersion over the catalyst surface because it has higher thermal conductivity than other supported catalysts. However, hydrogen selectivity of all support catalysts showed the similar result except for SBA-15 supported catalyst on which C₂H₄ and C₂H₆ were produced.
甘油是生物柴油生产过程中的主要副产物，但一直被当作废物丢弃。如果生物柴油能够实现商业化，甘油副产物的产量将迅速增加，因此需要一种重整技术将甘油用作高价值产品。在本研究中，测定了几种负载型催化剂对甘油水蒸气重整的催化活性。泡沫镍负载型催化剂的甘油转化率高于其他负载型催化剂，如氧化铝、整体式催化剂和SBA - 15。泡沫镍负载型催化剂在催化剂表面具有良好的热分散性，因为它比其他负载型催化剂具有更高的热导率。然而，除了负载在SBA - 15上能生成乙烯和乙烷的催化剂外，所有负载型催化剂的氢气选择性结果相似。
