摘要
以双氧水为氧化剂,研究均质氧化脱硫过程中高速分散均质机转速、反应时间、氧化剂油剂比及相转移催化剂等工艺条件对催化硫化(FCC)汽油模型化合物脱硫的影响情况。在高速分散均质机搅拌下,双氧水和有机酸催化剂反应生成过氧酸,然后相转移催化剂十六烷基三甲基溴化铵将生成的过氧酸转移到有机相中与FCC汽油中的含硫化合物发生氧化反应,生成极性较大的亚砜或砜类物质。
Using hydrogen peroxide as oxidant,the reaction of homogeneous oxidation desulfurization was studied.The effect of process conditions such as reaction time,speed of high speed dispersing homogenizer,oil/agent ratio catalyst and phase transfer agent on FCC gasoline desulfurization were studied.Under the stirring of high speed dispersive homogenizer,hydrogen peroxide reacted with organic acid catalyst to generate peroxide acid,and then transferred to the organic phase by the phase transfer catalyst cetyl trimethyl ammonium bromide.It could oxidize with sulfur compounds in FCC gasoline to generate sulfoxides or sulfones with large polarity.
