摘要
用浸渍法制备了负载型磷化钼氧化态前体,通过氢气程序升温还原磷钼酸盐的方法,制备了一系列不同MoP负载量及不同载体的催化剂,考察MoP负载量及不同载体对催化剂在二苯并噻吩转化率方面的催化性能。结果表明,MoP负载量为18%时,催化活性最高,以TiO_2/Al_2O_3复合体负载MoP的催化剂具有较高的催化活性。
An oxidized precursor of supported molybdenum phosphide was prepared with impregnation method, a series of catalysts of different MoP loading and different carriers were prepared, and the effects of MoP loading and different carriers on the performance of catalysts in catalyzing dibenzothiophene in terms of dibenzothiophene conversion were studied. The results of study have shown that the catalytic activity is the highest when MoP loading is 18% and that the catalytic activity of the catalyst with MoP supported by the composite carrier of TiO2 -Al2O3 is higher.
