Abstract

The invention provides a catalytic cracking oil slurry settling agent and application thereof. The catalytic cracking oil slurry settling agent is used for removing catalyst particles in catalytic cracking oil slurry. The catalytic cracking slurry oil settling agent comprises 10-60 omega t% of polycarboxylic acid polyether ester and 40-90 omega t% of aromatic hydrocarbon solvent oil, wherein the polycarboxylic acid polyether ester is a part of esterification product of esterification reaction of polycarboxylic acid and alkylphenol polyether. The catalytic cracking oil slurry settling agent has the advantages of simple raw materials, easiness in industrial production, environmental protection, no pollution, small filling amount and short settling time.

Description

technical field [0001] The invention belongs to the technical field of petroleum refining, and in particular relates to a sedimentation agent from catalytic cracking oil slurry and its application in removing catalyst particles. Background technique [0002] Catalytic cracking oil slurry (FCC oil slurry) is an important by-product of the catalytic cracking process, which has excellent economic value, but because the catalytic cracking oil slurry contains thousands to tens of thousands of ppm of catalyst solid powder, its utilization is greatly restricted. limit. In addition, when FCC oil slurry is used as a blending component of heavy fuel oil, if it is not purified, the catalyst particles in the oil slurry will accelerate the wear of the furnace burner, resulting in related problems such as the reduction of the efficiency of the heating furnace tube, so the removal of the oil slurry The catalyst particles in it are of great significance for the comprehensive utilization of...
