摘要：催化油浆是催化裂化生产过程中的副产品，催化油浆收率在4.1%~6.3%，重油的综合利

用成为炼油厂效益提升的重要环节。近年来，国内外对催化裂化油浆性质及其合理利用技术

进行了大量研究，归纳起来主要集中在2个方面。（1）将催化油浆与炼油工艺组合以合理利用

催化裂化油浆；（2）主要集中在利用催化裂化油浆生产不同的石油化工产品（如碳黑、针状焦

等）。某公司现有1套重油催化裂化装置，加工能力为450.0×104 t/a，正常的催化油浆外甩量

为9.5％，即外甩催化油浆42.7×104 t/a；还有1套蜡油催化裂化装置，加工能力为300.0×104 t/

a，正常的催化油浆外甩量为4％，即外甩催化油浆12.0×104 t/a。目前催化油浆仅送至延迟焦

化加工，该方案虽然可以解决催化裂化油浆的出路，但是对催化裂化油浆的利用效率低，经济

效益不理想，不是催化裂化油浆利用的最佳技术方案，且加工线路单一，因此，有必要寻找新

利用成为非常有研究价值的课题。

Abstract: Catalytic slurry is a byproduct of catalytic cracking production, with a yield of around 5%. The comprehensive utilizationof heavy oil has become an important link in improving refinery efficiency. In recent years, a large amount of research has beenconducted both domestically and internationally on the properties of catalytic cracking slurry and its rational utilization technology,which can be summarized into two main aspects: firstly, combining catalytic slurry with refining processes for the rational utilizationof catalytic cracking slurry; On the other hand, it mainly focuses on using catalytic cracking slurry to produce differentpetrochemical products (such as carbon black, needle coke, etc.). A certain company currently has a heavy oil catalytic crackingunit with a processing capacity of 4.5 million tons per year. The normal amount of catalytic slurry discharged is about 9.5%, whichmeans 427 500 tons of catalytic slurry are discharged annually; There is also a wax oil catalytic cracking unit with a processingcapacity of 3 million tons per year. The normal amount of catalytic slurry discharged is about 4%, which means 120 000 tons ofcatalytic slurry are discharged annually. At present, catalytic slurry is only sent to delayed coking processing. Although this solutioncan solve the problem of catalytic cracking slurry, its utilization efficiency of this valuable resource is low, and the economic benefitsare not ideal. It is not the best technical solution for the utilization of catalytic cracking slurry, and the processing route is single.Therefore, it is necessary to find new processing routes for catalytic slurry to obtain greater economic benefits. Catalytic slurrycontains approximately 10.8% saturated fraction, 70.2% aromatic fraction, 8.5% gum and asphaltene. If they can be effectivelyseparated and deeply processed, they can bring huge economic benefits. Saturated hydrocarbons are high-quality raw materials forcatalytic cracking, while aromatic hydrocarbons, gum, asphaltene, etc. are high-quality raw materials for producing carbon black,needle coke, heavy road asphalt, rubber filling oil, plastic plasticizers, thermal oil, carbon fiber, etc. The value-added utilization ofcatalytic cracking slurry has become a very valuable research topic.
