摘　　要：介绍增产柴油方案在抚顺石化公司催化裂化装置上的应用情况。工业试验结果表明:通过调整反应-再生系统、分馏系统操作参数和选用DMC-2增产柴油催化剂等措施,产品分布得到改善,柴油收率提高3.77百分点,轻质油收率提高1.81百分点,总液体收率提高1.06百分点,柴油与汽油质量比增加0.10。采取增产柴油方案后,柴油馏程拓宽,十六烷值略有下降;汽油烯烃含量下降,辛烷值基本不变,诱导期延长;对干气和液化气的质量无不良影响;装置能耗降低,总体经济效益每年可增加约3 772万元。The commercial trial of enhancing diesel fraction yield in the chemical Company was introduced. The trial results showed that by adopting FCC unit of Fushun Petro measures, such as adjusting operation parameters of reaction regeneration system and fractionation system, using DMC-2 catalyst designed for the increase of diesel yield,the product slates were improved： the yields of diesel fraction and light oils increased 3.77 and 1.81 percentage points,respectively; the mass ratio of diesel to gasoline in crease 0.10. As to the qualities of products, since the boiling range of diesel fraction was broadened, its cetane number was slightly lower; gasoline having lower olefin content,longer induction period and unchanged octane number; without negative effect was found on dry gas and LPG. Furthermore,the energy consumption of the unit was reduced. On the whole,a 37.72 million RMB economic benefit could be obtained annually.
