浅析美国推广生物燃料乙醇替代甲基叔丁基醚

由于甲基叔丁基醚（MTBE）的污染问题以及国际油价的持续高涨，生物燃料乙醇越来越受到美国社会公众的关注。生物燃料乙醇具有与MTBE相近的高辛烷值、良好的辛烷值调合效应、含氧量高达34．7％等特性，在技术和经济上都具有替代MTBE的可行性，美国大力推广生物燃料乙醇替代MTBE。针对美国禁用MTBE的趋势，对国内MTBE的生产和应用前景提出了发展建议。

A Tentative Discussion on Substituting Fuel Ethanol For MTBE in USA

Due to the pollution problem of MTBE, and the continuous uprising of international oil price, biological fuel ethanol has caused increasing attention of USA public. As biological fuel ethanol has similar features with MTBE like high octane number, good octane number blending effect, and high oxygen content up to 34.7%, it has the feasibility of substituting MTBE in technological and economic considerations. USA greatly popularizes the using of biological fuel ethanol to substitute MTBE. In view of the trend of prohibition of MTBE in USA, this paper raised proposals for production and application prospect of domestic MTBE.
