烷基化废硫酸的分析研究
|
摘要
烷基化油是理想的汽油调合组分,目前我国的烷基化生产装置主要以硫酸法为主,但烷基化油生产过程中会产生大量的废硫酸,该酸杂质较多,性质不稳定,很难回收处理。就烷基化废酸的密度、H+浓度、废酸与水不同体积比(1∶1、1∶1.25、1∶1.5、1∶2、1∶3)混合产生的固态沉淀物的量以及该沉淀物的溶解性等进行了实验研究。得出该固态沉淀物的回收率在体积比1∶1.25时最高为67.26%,在仲辛醇中的溶解性最好等。
Alkylate is the ideal blending component of gasoline. At present, the alkylation production equipment in our country mainly uses sulfuric acid process, but a large amount of waste sulfuric acid is produced during the production of alkylate. The waste acid contains many impurities, and its nature is unstable, so it is difficult to recycle the waste acid. In this paper, under different waste acid density and H+ concentration, when the volume ratios of waste acid and water were 1:1, 1:1.25, 1:1.5, 1:2 or 1:3, the amount and the solubility of solid precipitate were studied. The results showed that when the volume ratio was 1:1.25,the solid precipitate recovery was up to 67.26%, and its solubility in secondary octanol was the best.
