Abstract: Utilization of RFCC slurry oil has been limited by the content of solid impurity. How to resolve this problem is critical for subsequent production. Considering domestic catalytic slurry oil，Jinzhou Design Institute adopted the unique two-stage filtering technology of Pinfu Co.Ltd，and the majority of solid particles and asphaltene could be filtered by the first-stage filter. For the second-stage filter，metal powder-sintered filter elements with surface coating greatly improved opening efficiency and through flow and also the effect of backflush on filter elements. Offline washing of filter elements promised that filter elements could be reused after a work cycle. The content of solid particles in slurry oil after filtering was lower than 0.01 percent，which improved the quality of slurry oil produced.

摘要： 重油催化裂化油浆的开发具有重要的开发应用价值。但由于油浆含有一定量的固体杂质，限制了其利用率。因此，解决油浆固体含量过高的问题，是进一步开发下游产品的关键技术。针对国内催化油浆的特点，锦州设计院采用品孚公司的独特的二级过滤技术，在第一级过滤器上将大部分固体颗粒及沥青质过滤下来，对于第二级过滤器，采用表面镀膜的金属粉末烧结滤芯，极大地提高了滤芯表面的开孔率和可通过性，同时增大了反冲洗液对滤饼的作用力，提高了反冲洗效果。滤芯的离线清洗技术也可以保证用户的滤芯在使用一个周期后得到满意的再生。过滤后油浆的固体含量可达到0.01%以下，提高了油浆产品的品质。
