延迟焦化时，减压渣油中的沥青质在生成石油焦之前会生成中间相物质，它对石油焦形态结构的形成有重要的影响。传统的石油焦形成历程没有涉及中间相物质的结构，也没有指出为什么会出现不同形态的石油焦。根据中间相物质的定义，系统综述了中间相物质的产生及分离方法，详细介绍了对中间相物质分析表征的现代科学方法，旨在为当前深入探讨渣油生焦过程中弹丸焦的成焦机理和寻求预防对策提供帮助。

The mesosphase substance can be generated from the asphaltine of vacuume residue before the coke appears in delayed coking units. The formation of coke structure will be effected by the mesosphase substance. The traditional process of coke forming deals with nei- ther the structure of mesosphase substance nor the pattern of coke. Methods forming and separating mesosphase substance, and modem sci- entific methods characterizing mesosphase substance are detailedly introduced in this paper. These information is useful for us to research shot coke forming mechanism from vacuum residue pyrolysis and to explore the preventive countermeasure.
