| 摘 要： | 介绍了用一种碱性复合溶剂体系，在比较缓和的条件下，通过化学反应和抽提从直馏柴油中脱除石油酸的工艺过程。经实验室和中型试验研究，该工艺的石油酸脱除率达９０％以上，精制后柴油质量满足兰州炼油化工部总厂Ｑ／ＬＬＢ．１４０１－９１直馏柴油地企业标准；溶剂经加热可回收循环使用，得到的石油酸达到ＳＨ０５３０－９２的２号酸标准；该工艺不产生三废，有利于环境保护。

| Abstract: | Petroleum acids was removed from straight-run diesel distillate through chemical reaction and extraction under moderate conditions using an alkaline complex solution. This process is rather efficient with more than 90% of petroleum acid removed. The guality of the treated diesel fuel is high enough to meet the specification of Q/LLB. 1401-91. The reagents can be regenerated and used repeatedly. The recovered petroleum acids has a quality exceeding the requirements on grade-2 acid of SH053092. |
