1引言催化裂化轻汽油醚化工艺将催化裂化汽油中的叔碳烯烃转化为甲基叔烷基醚，不但可以提高辛烷值，增加含氧量，还可以降低蒸汽压和烯烃含量，因而是生产环境友好汽油的理想工艺。在催化裂化轻汽油醚化工艺的研究过程中，原料与产品需要快速准确的分析手段。本文采用气相色谱
1 Introduction Catalytic cracking of light gasoline etherification process Crude olefins from FCC gasoline are converted to methyl tertiary alkyl ethers, which not only increase the octane number, increase the oxygen content, but also reduce the vapor pressure and the olefin content. Therefore, The ideal process for producing environmentally friendly gasoline. In the FCC process of light gasoline etherification process, raw materials and products need fast and accurate analytical tools. In this paper, gas chromatography
