摘要(Abstract)：

以柠檬酸为络合剂,采用溶胶-凝胶法制备了非负载Ni-Mo复合氧化物催化剂,经过H2还原得到还原态催化剂。以环丁砜为反应原料,考察了还原条件对Ni-Mo复合氧化物催化剂结构及选择性加氢脱氧催化性能的影响。结果表明,非负载催化剂中NiO和MoO_3形成了复合氧化物NiMoO_4。NiMoO_4的形成降低了催化剂的还原温度;还原温度的升高和还原时间的延长有利于催化剂充分还原。催化剂的适宜还原条件为:还原温度400℃,H2流量45mL×min~(-1),还原时间3h;在0.3MPa,230℃,V氢气/V原料=200,1h~(-1)反应条件下,催化剂的性能是环丁砜的转化率为95.6%,四氢噻吩的选择性为86.2%。
