The invention relates to the technical field of petroleum refining and processing, in particular to an oil slurry solid removal agent, a preparation method and application thereof and a catalytic cracking oil slurry solid removal method. The solid removal agent for the oil slurry comprises a flocculating agent, a viscosity reducer and a solvent, wherein the structural formula of the flocculating agent is shown as a formula (I), and in the formula (I), n is 1-10; m is 2-4; and Ra and Rb are respectively selected from an unsubstituted alkylene chain or an alkylene chain containing a secondary ammonia structure. The flocculating agent with the structure shown in the formula (I) and the viscosity reducer are dissolved in the solvent to obtain the oil slurry solid removal agent, the settling period of solids in the oil slurry can be remarkably shortened, the cost is reduced, and the energy consumption is reduced. 本发明涉及石油炼制加工技术领域，具体涉及一种油浆脱固剂及其制备方法和应用以及催化裂化油浆脱固的方法。该油浆脱固剂包含絮凝剂、降粘剂和溶剂；其中，所述絮凝剂的结构式如式(I)所示，式(I)中，n为1-10；
