摘　　要：采用皂化反应和复分解反应合成了适用于重油悬浮床加氢裂化的非负载型环烷酸镍催化剂,并通过光学显微镜、激光粒度仪、XRD和SEM对该催化剂硫化后的性质进行了表征。结果表明,环烷酸和NaOH摩尔配比为1∶0.995、皂化反应温度为95℃,N iSO4溶液浓度为10%、复分解反应时间为2 h,复分解反应温度为90℃时,合成的催化剂中镍金属含量最高。通过釜式反应评价了该催化剂在委内瑞拉380号燃料油悬浮床加氢裂化反应中的催化效果,结果表明,该催化剂具有较好的抑焦效果。Unsupported nickel naphthenate catalyst which was good for slurry-bed hydrocracking of heavy oil was prepared through saponification and double-decomposition reactions, and the properties of the nickel naphthenate catalyst sulfurized were characterized using optical microscopy, laser hondrometer, X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The results showed that the metal content was highest when the tool ratio of naphthenic acid and NaOH was 1 ： 0. 995, saponification temperature was 95℃, the mass content of NiSO4 solution was 10%, double-decomposition time was 2 hours and double-decomposition temperature was 90 ℃. The catalytic effects of the unsupported nickel naphthenate in the slurry-bed hydrocracking of Venezuela 380# fuel oil were studied using autoclave, and the results demonstrated that the catalyst had a good performance of inhibiting coke formation.
