摘　　要：介绍了中国石油化工股份有限公司齐鲁分公司延迟焦化装置出现弹丸焦时的生产现象及影响;通过对生产过程的具体分析,发现产生弹丸焦时延迟焦化原料中沥青质质量分数达到了13%,Ni和V的质量分数达到了314μg/g,原料的残炭值与沥青质含量之比是1.4;提出了优化延迟焦化原料性质和操作参数的具体措施,在实施这些措施后避免了弹丸焦的产生,实现了装置安全和平稳生产。The shot coke formation and its impact on delayed coking unit are introduced. The analysis of the unit operation found that the feedstock of the coker contained 13% of asphaltene and 314 ppm of Ni and V. The feedstock＇s carbon residue to asphaltene ratio was 1.4. After improvement of feedstock properties and optimization of operating parameters, the production of shot coke has been avoided and safety and reliable operation has been ensured.
