中文摘要：针对催化装置开工后油浆固含量居高不下的情况，对影响油浆固含量的因素进行查找。通过分析实际工艺数据，与设计值进行比较，从催化剂流化的角度分析判断工艺操作使催化剂流化不正常，是导致油浆固含量高的主要原因。通过优化工艺，保持其它影响因素不变的前提下，将滑阀一次开度限制在2%以下，改善催化剂流化状态，化验分析发现油浆固含量由优化前的12-13g/L明显降至5-6g/L，完全满足公司对油浆固含量的要求。
英文摘要：In order to study the catalytic slurry oil device of high solid content, Analyze the influence factors of solid content of slurry, And put forward the measures to reduce solid content of slurry oil. Through the analysis of the actual process data, comparing with the designed value, technology make the catalyst fluidization abnormal operation,it is the leading cause of high solid content of slurry oil. By optimizing the process, improve the catalyst fluidization shape body, significantly reducing the slurry solids.
