Solid removal agent and method for deeply removing solid content in catalytic cracking oil slurry by using solid removal agent

The invention belongs to the technical field of fuel oil, particularly relates to a solid removal agent for pretreating and removing solid content in oil slurry, and further discloses a method for deeply removing ash solid content in catalytic cracking oil slurry. Under the synergistic effect of the main settling agent and the polymerization initiator, the solid removal agent has a unique removal effect on solid ash contained in high-viscosity catalytic cracking oil slurry, especially solid particles smaller than 20 microns, has the advantages of high solid removal efficiency and low energy consumption, and is simple and convenient to operate, low in operation cost and high in economic benefit. 本发明属于燃料油技术领域，具体涉及一种用于预处理脱除油浆中固体含量的脱固剂，并进一步公开一种深度脱除催化裂化油浆中灰分固含物的方法。本发明所述脱固剂在主沉降剂和聚合引发剂的协同作用下，对高粘度催化裂化油浆中所含固态灰分，尤其是小于20μm的固体颗粒有着独有的去除作用，具有脱固效率高、能耗低的优势，且操作简便、运行成本低、经济效益高。
