摘　　要：在固定流化床装置上进行了绥中高酸原油及其馏分油的催化裂化研究,在相同反应条件下考察了不同原料的脱酸率和产物分布,对比分析了绥中高酸原油切割前后催化裂化产物分布的变化以及全馏分催化过程中各馏分对产物分布的贡献。结果表明,绥中原油及其馏分油裂化性能较差,但不影响其催化裂化脱酸效果。绥中原油切割前后催化裂化的转化率和轻油收率变化不大,但柴油减少,汽油增加。全馏分催化时各馏分对产物分布的贡献不同,减压蜡油贡献最多的是汽油,而减压渣油贡献最多的是气体和柴油。The catalytic cracking of Suizhong highly acidic crude oil and its oil distillates is performed in fixed fluidized bed reactor. The influence of different feeds on the deacidification and products distribution is studied. The catalytic cracking product distribution before and after splitting the highly acidic crude oil, is compared. The contribution of each distillate to such a product distribution during the catalytic cracking of all-distillates is also discussed. The results show that although the crude oil and its distillates of Suizhong have poor cracking performance, the deacidification efficiency does not affected actually. The catalytic cracking conversion of Suizhong crude oil before and after splitting, and the light oil yield have little difference. However,the reduced diesel and increased gasoline can be observed. During the catalytic cracking of all-distillates, the distillates exhibit great influence on the product distribution. The vacuum gas oil mostly contributes to the increase of gasoline, while the vacuum residual oil mainly contributes to the increase of gas and diesel.
