摘　　要：研究了在Mo改性骨架Ni(S-NiMo)和负载型贵金属(Rh/C,Ru/C,Pd/C)催化体系下,芘选择性催化加氢的反应历程,并考察了以S-NiMo为催化剂时,溶剂、温度和压力对芘加氢反应的影响。实验结果表明,在负载型贵金属催化体系下,通过控制反应条件可使4,5,9,10-四氢芘成为主产物,催化剂活性高低顺序为:Rh/C>Ru/C>Pd/C,主产物收率高低顺序与其相反。而采用S-NiMo催化剂时,主产物为1,2,3,6,7,8-六氢芘;在该催化体系下,优化的反应条件为:以环己烷为溶剂,反应温度150℃,反应压力0.6 MPa,在此条件下,主产物1,2,3,6,7,8-六氢芘的收率达76.9%。Catalytic selective hydrogenations of pyrene over Mo modified skeletal Ni（S-NiMo） and supported noble metal catalysts, namely Rh/C, Ru/C and Pd/C, were studied. Effects of solvent type, reaction temperature and reaction pressure on the pyrene hydrogenation over S-NiMo catalyst were investigated. The main product was 4,5,9,10-tetrahydropyrene over the supported noble metal catalysts. Catalytic activities of different catalysts for the pyrene hydrogenation was found in the order of Rh/C 〉 Ru/C 〉 Pd/C, which was opposite to the main product yield. 1, 2, 3, 6, 7, 8- hexahydropyrene was mainly obtained in the pyrene hydrogenation over S-NiMo catalyst, and its yield was up to 76.9% under the optimal conditions of reaction temprature 150℃, pressure 0.6 MPa and cyclohexane as the solvent.
