车用燃料油精制脱硫的研究与发展

降低车用燃料油中硫含量对于提高机动车尾气排放质量从而保护环境具有十分重要的意义。着重对催化加氢及非催化加氢脱硫两类加氢工艺的特点进行了比较,介绍了国内外车用燃料油精制脱硫的研究与发展。针对开发新配方汽油及低硫、低芳烃柴油的要求,提出了今后燃料油脱硫的研究方向为:具有较高选择性的汽油加氢脱硫催化剂和新工艺;具备高效加氢脱硫和芳烃饱和活性的新一代柴油改质催化剂和新工艺;同时应重视非催化加氢脱硫技术的应用研究。

Research and development in deep desulfurization of motor fuel

The reduction of sulfur impurities in motor fuel plays a significant role in improving tail gas quality and protect-ing environment. Comparisons of technical features between catalytic process and non-catalytic process are made. Researches and developments in deep desulfurization of motor fuel both at home and abroad are introduced. Some key areas of basic research oriented to the development of new catalysts with high selectivity and new techniques for producing gasoline with new formulation and diesel with low sulfur and low aromatics are recommended. Application research of non-catalytic desulfurization technique should be emphasized.
