Preparation of Dispersive Cobalt Naphthenate Catalyst and Its Application in Suspended-Bed Hydrocracking of Heavy Oil
采用皂化反应和复分解反应合成了适用于重油悬浮床加氧裂化反应的分散型环烷酸钴催化剂,并优化了合成条件；通过光学显微镜、激光粒度仪、XRD和SEM方法对硫化后的催化剂进行了表征；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性能.实验结果表明,合成分散型环烷酸钴催化剂的优化条件为:在皂化反应中,NaOH质量分数15％,环烷酸与NaOH摩尔比1:0.995,皂化温度95℃,皂化时间3h;在复分解反应中,CoSO4溶液质量分数1…查看全部>>
A dispersive cobalt naphthenate catalyst which was used in suspended-bed hydrocracking of heavy oil was prepared through saponification and double-decomposition, and the catalyst after sulfurization was characterized by means of optical microscopy, laser scattering particle analyzer, XRD and SEM. The effect of the catalyst on the suspended-bed hydrocracking of Venezuela 380* fuel oil was studied in a autoclave. The results showed that the optimal preparation…查看全部>>
