摘　　要：研究了负载在Al2O3载体上的贵金属钯基催化剂对重整重芳烃油选择性加氢脱烯烃反应的性能。以重整残余重芳烃油为原料,分别对催化剂载体、贵金属负载量和助剂添加量进行考察。结果表明,700℃焙烧混有2%Ni的γ-Al2O3和负载0.2%的贵金属Pd综合效果最理想。催化剂稳定性结果表明,催化剂在500 h能保证产品溴指数在200 mg-Br.(100g)-1以下,原料中萘环的损失在2%以下。The performance of palladium supported catalysts for selective hydrogenation and deolefin of reforming heavy aromatic oil was studied. The catalyst supports, loadings of noble metal and the additive were investigated using the reforming residual heavy aromatic oil as the raw material. The results showed that the catalyst with the loadings of 2% Ni and 0.2% Pd on y-A1203 and calcined at 700 ℃ exhibited ideal catalytic properties. The experimental results of the catalyst stability indicated that the product bromine index of less than 200 mg-Br · （ 100 g） -1 and the loss of naphthalene ring of less than 2% in the raw material were attained over the catalyst within 500 h.
