摘　　要：催化油浆因具有丰富的碳源优势,已经应用于石油化工领域及其他经济领域,但实现其经济价值的前提是必须进行脱固处理。以大庆某炼厂催化油浆为研究对象,采用超声辅助化学沉降法对催化油浆进行脱固处理,主要考察了剂油比、温度、超声时间等因素对催化油浆脱除效率的影响,判断超声与化学沉降法组合应用是否发挥协同作用,加强脱除效果。研究结果表明:采用环己烷和聚丙烯酰胺为化学助剂,丙三醇水溶液为水相溶液的化学沉降法对催化油浆进行脱除固体颗粒实验时,催化油浆中催化剂颗粒的脱除率为89%;化学沉降法和超声联用,在超声频率40 k Hz,超声时间10 min条件下,催化油浆的脱除率可达到94%以上。这说明超声辅助作用能够强化催化油浆的脱除效果。The FCC slurry has been used in petrochemical industry and other economic fields because of its advantage of rich carbon source,but the premise of realizing its economic value is to remove the catalyst particles.The FCC slurry from a Daqing refinery plant is used as the research ob-ject to study the removal of catalyst particles by ultrasonic treatment assisted chemical sedimentation method,the effects of ratio of agent to oil,tem-perature and ultrasonic time on the removal efficiency for FCC slurry are researched,and it is determined that if there is a synergy created by ultra-sonic combined with chemical sedimentation method and enhances the removal effect.The results show that when the cyclohexane and polyacrylamide are used as chemical additives and the glycerin aqueous solution is used as aqueous phase solution,the removal rate of catalyst particles from FCC slurry is 89%.At an ultrasonic frequency of 40 kHz,the removal rate can reach more than 94%in an ultrasonic time of 10 min,this indicates that the assisted ultrasonic treatment can enhance the removal effect for FCC slurry.
