摘　　要：通过分析7种典型催化裂化油浆(简称油浆)性质及固体颗粒的粒度分布,发现不同来源的油浆性质差异较大,油浆中绝大部分固体颗粒粒径小于50μm,其中粒径为1~10μm的固体颗粒体积分数超过50%。采用3代柔性滤材开展油浆脱固试验,结果表明,第三代滤材对油浆的脱固率最高,(Al+Si)脱除率超过97%,滤材再生性能好。在氢分压为3.0 MPa的条件下,开展油浆低压临氢脱固脱硫工艺研究,结果表明,该工艺原料适应性好、产品质量稳定。以脱固脱硫油浆和加氢渣油为组分开展低硫重质船用燃料油调合试验研究,调合时多数性能指标符合线性规律,经济性调合配方中油浆的质量比例高于30%。By analyzing the properties and solid particle size distribution of seven typical FCC slurries,it was found that the properties of slurry from different sources were quite different,the particle size of most solid particles in the slurry was less than 50μm,and the volume fraction of particles with diameter of 1—10μm was more than 50%.Three generations of flexible filter materials were used for FCC slurry desolidification experiments.The results showed that the third generation filter material had the highest desolidification rate for FCC slurry,(Al+Si)removal rate was over 97%,and the filter material regeneration performance was good.Under the condition of hydrogen partial pressure of 3.0 MPa,the desulfurization process of slurry under low pressure was studied.The results exhibited that the process has good adaptability of feedstocks and stable product quality.The blending of low sulfur heavy marine fuel oil with desulfurized and desolidified slurry as well as hydrogenated residue as components was carried out.Most of properties indexes of the blending accord with the linear law,and the mass ratio of FCC slurry in the economic blending formula is higher than 30%.
