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。
