| 摘 要： | 以硝酸镍为镍源、磷酸为磷源,与硅溶胶按一定比例混合,制成混合物浆料,然后采用浸渍法将混合物浆料负载于处理好的堇青石蜂窝陶瓷载体上,经过干燥、焙烧后制得含磷化镍前驱体的整体式催化剂,再经氢气气氛下程序升温还原,制得一系列不同镍含量的磷化镍/SiO2/堇青石整体式催化剂.采用XRD、N2吸脱附和SEM等现代分析测试手段对催化剂的结构进行了表征.以二苯并噻吩为模型含硫化合物,对催化剂的加氢脱硫活性进行了评价.结果表明,磷化镍/SiO2/堇青石整体式催化剂中,Ni含量小于3.2wt%时,磷化镍在堇青石表面高度分散,Ni含量大于6.4wt%时,催化剂的活性相是Ni2P,催化剂的平均孔径在3.6nm左右.催化活性层平均厚度约为20μm.在液时空速(LHSV)为1.9 h-1时,Ni含量为12.8wt%的催化剂具有最高的加氢脱硫活性,在360℃时二苯并噻吩的转化率为92.0%,联苯的选择性为69.8%,环己基苯的选择性为30.2%,反应主要按直接脱硫机理进行.
