相转移催化氧化体系在燃料油脱硫中的应用

Applications of phase transfer catalytic oxidation system in the desulfuration of fuel oil

介绍了以过氧化氢为氧化剂的相转移催化氧化脱硫研究现状。对过氧化氢/有机酸/季铵盐体系、过氧化氢/杂多酸/季铵盐体系和过氧化氢/合成相转移催化剂体系在脱除燃料油中噻吩、苯并噻吩、二苯并噻吩等方面的应用作了综述。指出了过氧化氢/合成相转移催化剂体系是燃料油深度脱硫的一个重要研究方向。

Present situation of research on the phase transfer catalytic oxidative desulfuration employing hydrogen peroxide as oxidizing agent was introduced.Usage of hydrogen peroxide/organic acid/quaternary ammonium salt,hydrogen peroxide/heteropolyacid/quaternary ammonium salt and hydrogen peroxide/compound phase transfer catalyst systems in the removal of thiophene,benzothiophene,dibenzothiophene were reviewed.It can be concluded that hydrogen peroxide/compound phase transfer catalyst system is an important direction of research in the deepdesulfurization of fuel oil.
