FCC油浆中催化剂颗粒的超声辅助脱除研究

Research on Ultrasonic Assisted Removal of Catalyst Particles in FCC Slurry

炼厂FCC油浆中含有一定量的固体催化剂颗粒,固体催化剂颗粒的存在对油浆的深加工和综合利用均有不利影响。本文以某公司1#催化装置FCC油浆试样为例,考察了超声波对FCC油浆脱除固体催化剂颗粒的影响。在超声波频率40k Hz下处理20min,采用离心法测得固体催化剂含量为6.4g·L^(-1)。结果表明,超声波辅助手段能有效促进FCC油浆中催化剂颗粒的脱除。

Refinery FCC slurry contained a certain amount of solid catalyst particles, the presence of solid catalyst particles had a detrimental effect on the deep processing and comprehensive utilization of the slurry. This paper investigated the effects of ultrasonic on the removal of solid catalyst particles from FCC slurry. Under the condition of ultrasonic frequency 40kHz for 20min, the solid catalyst content was 6.4 g/L by centrifugation. The results showed that the ultrasonic assisted method could effectively promote the removal of catalyst particles in FCC slurry.
