摘要: 将裂解焦油以不同比例掺炼到延迟焦化原料油中,考察产品分布和产品性质。结果表明,掺炼裂解焦油后干气、液化气收率减少,汽油、柴油、蜡油收率变化不明显,焦炭收率增加,主要产品硫、氮、金属质量分数有所降低。

Abstract: Daqing pyrolysis tar was mixed into delayed coking feed under various blending ratios, and their effects on the product slates and product quality were investigated. Results showed that as compared with the base case, after mixing pyrolysis tar in the feed the yields of dry gas and LPG were reduced, the yields of gasoline, diesel fuel and heavy oil were basically unchanged, yet the coke yield was increased; the contents of sulfur, nitrogen and metals in the main products were slightly decreased.

Key words: pyrolysis tar, delayed coking, product quality
