Description

technical field [0001] The invention relates to the field of comprehensive utilization of catalytic cracking oil slurry, in particular to a pretreatment device, system and pretreatment method of catalytic cracking oil slurry. Background technique [0002] As the global petroleum resources become more and more heavy, catalytic cracking (Fluid catalytic cracking, FCC) is becoming more and more important as an advanced technology for heavy oil processing. The annual processing volume of catalytic cracking in my country exceeds 150 million tons, and the output of oil slurry accounts for about 5% to 10% of the treatment volume of catalytic cracking. The output of oil slurry, a by-product of catalytic cracking, also increases year by year. The properties of catalytic cracking oil slurry are very special. The components are mainly polycyclic aromatic hydrocarbons, generally without long alkyl side chains, and the average relative molecular weight is relatively large, about 500, whi...
