摘　　要：近几年,国内汽油市场需求增长高于柴油需求增长,成品油消费结构逐渐发生了变化,市场需求柴汽比不断降低。介绍了某炼油厂优化生产方案、降低柴汽比取得的较好效果。采取增产催化裂化及连续重整装置原料、提高催化裂化及连续重整装置负荷、重整汽油重组分馏分进催化裂化回炼等措施,柴汽比逐年降低,2012年柴汽比达到1.23∶1,比设计值降低20%,相当于减产柴油增产汽油359.1 kt/a,增效24 781×104RMB$/a。As the increase of gasoline demand is higher than the diesel demand in China and structure of product oil consumptions changes in the past several years, the demand of diesel/gasoline ratio is gradually de- creased. The good results of reducing the diesel to gasoline ratio in a refinery have been achieved through opti- mization of production schemes. The diesel to gasoline ratio is gradually lowered through increase in production of FCC and CCR feedstocks as well as their operating capacities and heavy reformate is recycled to FCCU, etc. The diesel to gasoline ratio was 1.23：1 in 2012, a 20% decrease as compared to an increase of 359,100 tons of gasoline per year and a economic benefit of with the design, which is equivalent 247.81 million Yuan RMB a year.
