摘　　要：考察了采用不同溶解方式对活性的影响,磷源对催化剂性能的影响以及不同含量的磷对催化剂的影响。结果表明,磷源对催化剂的结构影响较小,但是对活性有比较大的影响,其中以磷酸氢二铵作为磷源时重整活性最好。并考察了催化剂失活再还原后测定其活性和催化剂的稳定性,钝化后还原和新鲜态的催化剂评价其重整活性时,差别很小。并用H2-TPR和CO2-TPD技术表征了所制磷化钼催化剂的表面性质。The impact on the activity in the different process of dissolution was studied in the paper,the source of phosphorus catalyst performance,as well as different levels of phosphorus catalyst.The results showed that the smaller effects on the structure of catalysts of phosphorus source.However,a relatively larger impact on the activity,with diammonium phosphate as phosphorus sources the best reforming activi-ty was observed.Little difference was found in the measured activity and catalyst deactivation of the cata-lyst.By using H2-TPR and CO2-TPD techniques,the surface properties of the molybdenum phosphide cata-lysts were characterized.
