| 摘 要： | 用碳酸钠作为脱酸剂脱除柴油中的酸。考察了脱酸工艺中各因素对脱酸效果的影响,获得了柴油脱酸的工艺条件:剂油比为0.35∶1,反应温度为330K,搅拌时间为7min,静置时间为30min。在最佳工艺条件下柴油酸度由135.52mgKOH/100mL降至5.69mgKOH/100mL,脱酸率达到95.8%,精制后柴油中的水分含量为1.4%,柴油的回收率为94.6%,达到了柴油合格指标。

| Abstract: | Sodium carbonate as deacidification agent was used to remove naphthenic acid from diesel oil.The influence of factors about treating conditions on the acid removal from diesel oil was investigated,such as volume ratio of deacidification agent-to-oil(VRDO),reaction temperature,stirring time and resting time.The results showed that the optimum condition was that VRDO was 0.35∶1,reaction temperature was 330K,stirring time was 7min,and resting time was 30min.Under the optimum condition,acidity of diesel oil was reduced to 5.69mgKOH/100mL from 135.52 mgKOH/100mL,and deacidification rate of naphthenic acid reached 95.8%,the water content in the diesel oil was 1.4%,diesel oil recovery reached 94.6%,the quality index of diesel meets the national standard. |
