摘　　要：研究了CuO与FCC汽油碱精制碱渣中硫化物反应,脱除碱渣中恶臭物质,置换出NaOH反应的影响因素。结果表明,在CuO与Na_2S的摩尔比为1.3～1.4,反应温度为40～50℃,反应时间为30 min的再生条件下,再生碱液中游离碱浓度可达到107g/L以上,碱渣中无机硫脱除率可达99%以上,FCC汽油碱精制碱渣得到再生。The impact factors of reaction of CuO with sulfides in the spent caustic from FCC gasoline refining, the foul substance and the NaOH restoration were studied by experiments. At the reaction conditions of 40-50℃ temperature, 30 minutes＇ reaction time and a CuO to Na2S ratio （mole） of 1.3 - 1.4, the removal rate of inorganic sulfides was over 99% and the free NaOH was higher than 107 g/L in the regenerated caustic. Therefore, the spent caustic of FCC gasoline refining was successfully regenerated.
