Influencing Factors and Control Methods of Circulating Acid Concentration in Sulfuric Acid Isooctane Synthesis Reaction

硫酸法异辛烷合成反应是指在以硫酸为催化剂的条件下,异丁烷与烯烃发生加成反应,生成高辛烷值的异辛烷。硫酸作为异辛烷合成反应的催化剂,反应过程中循环酸浓度的控制是很重要的,不同的循环酸浓度对异辛烷合成油的辛烷值和收率都有显著影响,异辛烷合成反应循环酸浓度一般控制在93%~97%。主要从异辛烷合成反应过程中循环酸浓度的影响因素和酸浓度的控制进行阐述,目的是对异辛烷合成反应循环酸浓度的控制提出改进意见。

The sulfuric acid isooctane synthesis reaction refers to the chemical addition reaction of isobutane and olefins under the condition of using sulfuric acid as a catalyst to produce isooctane with a high octane number.Sulfuric acid is used as a catalyst for the synthesis of isooctane.The control of circulating acid concentration during the reaction is very important.Different circulating acid concentrations have a significant effect on the octane number and yield of isooctane synthesis oil.The reaction cycle acid concentration is generally controlled at 93 to 97%.This paper mainly expounds the influencing factors of circulating acid concentration and the control of acid concentration in the process of isooctane synthesis reaction.The purpose is to put forward suggestions for improving the control of circulating acid concentration in isooctane synthesis reaction.
