重质油悬浮床加氢技术新进展

综述了重质油悬浮床加氢工艺的最新进展,并对分散型催化剂的开发进展进行了系统的总结.重质油悬浮床加氢催化剂经历了非均相固体粉末催化剂和均相分散型催化剂两个过程,均相分散型催化剂又分为水溶性分散型催化剂和油溶性分散型催化剂两类.非均相固体粉末催化剂催化活性较低,而且致使尾油中含有大量的固体颗粒,处理和利用困难较大.分散型催化剂分散度较高,比表面积大,催化活性高,性能优越,是一种较为理想的催化剂.简要介绍了中国石油天然气股份有限公司和中国石油大学联合开发的新型重油悬浮床加氢技术.

NEW DEVELOPMENT OF SLURRY-BED HEAVY OIL HYDROCRACKING PROCESS

The latest development of slurry-bed heavy oil hydrocracking process and dispersant catalyst are reviewed. Catalyst for slurry bed hydrocracking of heavy oil has undergone two development phases, i.e. nonhomogenous solid powder catalyst and homogenous dispersant catalyst. The homogenous catalysts are divided into water-soluble dispersant catalyst and oil-soluble dispersant catalyst. Solid powder catalyst has lower catalytic activity, which will produce a large amount of solid particles in tail oil difficult to treat and utilize. Dispersant catalyst has higher degree of dispersion and greater specific surface to volume ratio. Therefore, it has high catalytic activity and good performances. It is a desirable catalyst for slurry-bed hydrocracking of heavy oil. The new process of slurry-bed heavy oil hydrocracking developed by PetroChina Co. , Ltd. and China University of Petroleum is described.
