摘　　要：在内径为16 mm、长度为600 mm的管式反应器中,研究了过渡金属Ni,Mo改性后的活性氧化铝催化生物柴油脱羧的效果,比较了活性氧化铝分别经Ni,Mo的氧化态、还原态改性后,催化生物柴油脱羧的活性变化。得出结论:利用过渡金属Mo的氧化态、还原态改性后,氧化铝的催化性能有明显的提高;利用过渡金属Ni改性后,氧化铝的催化性能基本没有变化。当以还原态的Mo改性后的氧化铝作为脱羧催化剂时,可得到最高约89.23%的酯转化率及37.32%的液态烃产率。Decarboxylation of biodiesel using the activated alumina as catalyst in a tubular reactor with the internal diameter of 16 millimeter and the length of 600 millimeter was studied. The activatedalumina was modified by Ni and Mo. The effects of different type of Ni and Mo modifying activated alumina on the decarboxylation of biodiesel were investigated. It was concluded that the activity of activated alumina on decarboxylation of biodiesel was greatly increased when it was modified by Mo with the oxidation state or the reduced state. However, the activity of activated alumina was hardly changedwhen it was modified by Ni. It was achieved about 89.23% conversion of biodiesel and 37.32% yield of liquid hydrocarbon when using activated alumina which was modified by the reduced state of Mo as the catalyst.
