汽油中有害物质检测及脱除方法的研究进展

Research progress on detection and removal of harmful substances in gasoline

高品质汽油的制备生产对我国的健康可持续发展意义重大,既可以加快我国工业化和城镇化的进程,又能够改善我国空气环境的质量,缓解日益严重的能源危机。鉴于我国当前汽油质量的现状,对车用汽油中有害物质进行严格的检测及有效脱除是一项极其重要的工作。本文首先对车用汽油中常见有害物质如硫化物、甲基苯胺类化合物、甲缩醛和乙酸异丁酯等的检测方法进行了总结概括,分析其当前的研究进展,接着对汽油中常见有害物质硫化物的脱除方法进行了分类和比较,重点综述了催化氧化法、烷基化法、吸附法和渗透汽化法。

The preparation and production of high-quality gasoline is of great significance to the healthy and sustainable development of our country.It can not only accelerate the process of industrialization and urbanization,but also improve the quality of air environment and alleviate the increasingly serious energy crisis.In view of the current situation of gasoline quality in China,it is an extremely important task to strictly detect and effectively remove harmful substances in automotive gasoline.In this paper,the detection methods of common harmful substances in automotive gasoline such as sulphides,methylaniline compounds,methylaldehyde and isobutyl acetate are summarized,and the current research progresses are also analyzed.The removal methods of common harmful substance sulphides from the gasoline are classified and compared,with the emphasis on catalytic oxidation,alkyla-tion,adsorption and pervaporation.
