- W973693301 abstract "以硝酸镍为镍源,磷酸氢二铵为磷源,介孔分子筛SBA-15为载体,用共浸渍法制备了含磷化镍前驱体的样品,然后在氢气流中采用程序升温还原法,制备了Ni2P质量分数为5%-40%的Ni2P/SBA-15催化剂.用X射线衍射（XRD）、N2吸附脱附、透射电子显微镜（TEM）、傅立叶变换红外光谱（FTIR）等分析测试技术对催化剂的结构进行了表征,以噻吩和二苯并噻吩（DBT）为模型化合物,在微型固定床反应器上对催化剂的加氢脱硫（HDS）性能进行了评价.结果表明,Ni2P/SBA-15催化剂中SBA-15的介孔结构依然存在,活性组分Ni2P具有良好的分散性,但随Ni2P含量的增加,催化剂的比表面积、孔容和孔径均有明显减小.当反应温度为320℃时,Ni2P含量为15%-25%（w）的催化剂就具有很好的加氢脱硫催化性能;反应温度在360℃以上时,所有催化剂都具有优异的深度脱硫催化性能.Ni2P/SBA-15催化剂对二苯并噻吩的加氢脱硫（HDS）主要以直接脱硫机理（DDS）进行." @default.
