The present invention deals with a process for sweetening a sour hydrocarbon fraction containing mercaptans. The process involves contacting the hydrocarbon fraction with a catalytic composite in the presence of an oxidizing agent, ammonium hydroxide and a quaterary ammonium salt. The instant process does not use any strong base nor any alkali hydroxides to sweeten the sour hydrocarbon fraction and thus obviates waste disposal problems.
本发明涉及一种使含有硫醇的酸性烃馏分甜化的工艺。该工艺包括在氧化剂、氢氧化铵和四价铵盐存在的情况下,将烃馏分与催化复合材料接触。本工艺不使用任何强碱或碱氢氧化物来甜化酸性烃馏分,因此避免了废物处理问题。
