Process for preparing a sweetened hydrocarbon liquid composition with reduced tendency to form gums, a scavenger composition for use in said process, and the sweetened hydrocarbon liquid composition with reduced tendency to form gums so prepared.

摘要

The invention provides a process for preparing a sweetened hydrocarbon liquid composition with reduced tendency to form gums from a sour hydrocarbon liquid composition containing 5 mercaptans and with an olefin content of 5 vol.% or more, by reacting the mercaptans in the sour hydrocarbon liquid composition into disulfides with an oxidizing agent in the presence of a scavenger composition comprising a cobalt complex as catalyst and a strong base, wherein the strong base consists of KOH. Also provided is a scavenger composition comprising the catalyst and the base that may be used in the process of the invention, and a 10 sweetened hydrocarbon liquid composition with reduced tendency to form gums.
