The non-sulfided Ni-PTA/Al2O3 catalyst was developed to produce green diesel from the hydroprocessing of Jatropha oil. The Ni-PTA/Al2O3 catalyst was prepared by one-pot synthesis of Ni/Al2O3 with the co-precipitation method and then impregnanting Ni/Al2O3 with PTA solution. The catalysts were characterized with BET, SEM-EDX, TEM, XRD, XPS, TGA and NH3-TPD. The Ni and W species of the Ni-PTA/Al2O3 catalyst were much more homogeneously distributed on the surface than that of commercial Al2O3. Catalytic performance in the hydroprocessing of Jatropha oil was evaluated by GC. The maximum conversion of Jatropha oil (98.5 wt%) and selectivity of the C15-C18 alkanes fraction (84.5 wt %) occurred at 360 °C, 3.0 MPa, 0.8 h(-1). The non-sulfided Ni-PTA/Al2O3 catalyst is more environmentally friendly than the conventional sulfided hydroprocessing catalyst, and it exhibited the highest catalytic activity than the Ni-PTA catalyst supported with commercial Al2O3 grain and Al2O3 powder.
开发了非硫化的Ni-PTA/Al2O3催化剂，用于麻风树油加氢处理生产绿色柴油。采用共沉淀法一锅合成Ni/Al2O3，然后用PTA溶液浸渍Ni/Al2O3制备Ni-PTA/Al2O3催化剂。采用BET、SEM-EDX、TEM、XRD、XPS、TGA和NH3-TPD对催化剂进行了表征。与商业Al2O3相比，Ni-PTA/Al2O3催化剂的Ni和W物种在表面分布更均匀。通过GC评价了麻风树油加氢处理的催化性能。在360 °C、3.0 MPa、0.8 h(-1)条件下，麻风树油的最大转化率（98.5 wt%）和C15-C18烷烃馏分的选择性（84.5 wt%）出现。非硫化的Ni-PTA/Al2O3催化剂比传统的硫化加氢处理催化剂更环保，并且比负载在商业Al2O3颗粒和Al2O3粉末上的Ni-PTA催化剂表现出最高的催化活性。
