一直以来，人们在煤系针状焦生产的原料选择上认为煤沥青为大众原料，只要物化指标符合要求即可选择使用。通过在生产过程中采取不同产地、不同厂家的两种沥青按照不同的比例混配，在控制其理化指标相近或相似的情况下，经过大量的生产数据整理与总结发现：具有相似指标的煤沥青，用于延迟焦化生产反应过程中的热解产物、产品收率以及产品质量是有差异的。因此，在针状焦的生产过程中原料沥青的选择方面，不能完全依赖几个物化指标，也应该重视不同产地沥青的使用性能，重视实际生产过程中的技术研究所积累的经验。

All the time the coal tar pitch is thought as the preferred selection raw material for the production of coal-based needle cokes, as long as the physical and chemical indexes meet the requirements. In this paper the coal based needle cokes were produced using two pitches as feedstock from different producing manufacturers with the different mixing ratio, through controlling their chemi-cal indicators close or similar. A number of production data were achieved. The results showed that there are the differences in py-rolysis products, such as product yield and product quality of the delayed cokes from pitches with the similar properties during cok-ing. Therefore, the choice of raw material of pitch in the process of needle coke production can not rely solely on several physical and chemical indicators, should also be paid attention to the performance of pitch from different sources of origin and the experience accumulated during the production processes.
