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450.0×10^(4)t/a,正常的催化油浆外甩量为9.5%,即外甩催化油浆42.7×10^(4)t/a;还有1套蜡油催化裂化装置,加工能力为300.0×10^(4)t/a,正常的催化油浆外甩量为4%即外甩催化油浆12.0×10^(4)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,有必要寻找新的催化油浆加工路线。催化油浆中含10.8%的饱和分、70.2%的芳香分、8.5%的胶质和沥青质,饱和烃是优质的催化裂化原料,芳烃、胶质、沥青质等是生产炭黑、针状焦、重质道路沥青、橡胶填充油、塑料增塑剂、导热油、碳纤维等的优质原料,如何将其有效分离,深度加工并增值利用成为非常有研究价值的课题。Catalytic slurry is a byproduct of catalytic cracking production,with a yield of around 5%.The comprehensive utilization of heavy oil has become an important link in improving refinery efficiency.In recent years,a large amount of research has been conducted 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 utilization of catalytic cracking slurry;On the other hand,it mainly focuses on using catalytic cracking slurry to produce different petrochemical products(such as carbon black,needle coke,etc.).A certain company currently has a heavy oil catalytic cracking unit with a processing capacity of 4.5 million tons per year.The normal amount of catalytic slurry discharged is about 9.5%,which means 427500 tons of catalytic slurry are discharged annually;There is also a wax oil catalytic cracking unit with a processing capacity of 3 million tons per year.The normal amount of catalytic slurry discharged is about 4%,which means 120000 tons of catalytic slurry are discharged annually.At present,catalytic slurry is only sent to delayed coking processing.Although this solution can solve the problem of catalytic cracking slurry,its utilization efficiency of this valuable resource is low,and the economic benefits are 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 slurry contains approximately 10.8%saturated fraction,70.2%aromatic fraction,8.5%gum and asphaltene.If they can be effectively separated and deeply processed,they can bring huge economic benefits.Saturated hydrocarbons are high-quality raw materials for catalytic cracking,while aromatic hydrocarbons,gum,asphaltene,etc.are high-quality raw materials for producing carbon b
