摘要
随着城市汽车拥有量的不断增加,汽车尾气已成为城市大气的主要污染源,尤其是尾气中的SOX和NOX对环境的危害更大。为改善大气质量,就必须降低成品汽油的硫含量。催化裂化汽油是成品汽油的重要组成部分,其硫含量的高低直接影响着成品汽油的硫含量。目前,国内外降低催化裂化汽油硫含量的方法主要有催化裂化汽油加氢脱硫、溶剂抽提脱硫、催化裂化脱硫、氧化脱硫、生物脱硫及吸附脱硫。本文综述了各种脱硫方法的国内外发展状况。
With the increase of motors in the city,motor exhaustion has been the main pollution of atmosphere in the city.Especially,SO_X and NO_X do harm to environment.For making the atmosphere quality better,sulfur content of gasoline product must be reduced.FCC gasoline is important component of gasoline product,whose sulfur content influences sulfur content of gasoline product directly.At present,means of reducing sulfur content of FCC gasoline include FCC Gasoline hydrodesulfurization,solvent extraction desulfurization,catalytic cracking desulfurization,oxidative desulfurization,biodesulfurization,and adsorption desulfurization.Domestic and foreign development of means of each desulfurization is outlined.
