The results show that catalytic properties of catalysts modified by Cr and Mo are improved remarkably and Cr 2O 3 and MoO 3 in the catalysts have the property of donating electrons towards Cu particles. Adding proper amounts of Cr, Mo to catalysts can increase the dispersity of Cu particles and the stability of catalysts.

The catalysts for hydrotreating process are widely used in petroleum industry and more and more studies are focused on the reuse of spent catalysts because of the environmental regulation and the high catalyst consumption. NiMo/ γ Al 2O 3 is one of the most important catalysts for the hydrodesulfurization (HDS)/hydrodenitrogenation (HDN) in petroleum industry.

The catalysts for hydrotreating process are widely used in petroleum industry and more and more studies are focused on the reuse of spent catalysts because of the environmental regulation and the high catalyst consumption. NiMo/ γ Al 2O 3 is one of the most important catalysts for the hydrodesulfurization (HDS)/hydrodenitrogenation (HDN) in petroleum industry. In this study, the effect of regeneration conditions on the physico chemical properties and catalytic performance of the spent catalysts was investigated. The regenerated samples were characterized by low temperature nitrogen adsorption, XRD, SEM EDS, IR and TPR techniques. The catalytic activities of regenerated samples were evaluated by catalytic hydrodesulfurization of diesel oil. The results show that for the samples regenerated at a suitable temperature, there is only a little change in the textural structure, the aggregate of active phase in the oxidized samples may change the coordination states of some active elements, decrease the reduction temperature and improve the HDS activity of the regenerated samples. The existence of sulfate ions does not affect the HDS activity of the regenerated catalysts.

NiMo/γ-Al2O3是石油加工过程中广泛采用的加氢催化剂,有关这类催化剂的制备、结构、催化机理等都进行过深入的研究[1,9,10].近年来,由于环境保护的要求日益严格,失活催化剂的处理已成为突出的问题,因此失活的加氢催化剂的再生利用已引起了工业界...
