PROCESS FOR REMOVING SULFUR COMPOUNDS FROM HYDROCARBONACEOUS STREAMS

摘要

In a method for removing sulfur compounds, selected among thiols (R-SH), organic sulfides (R-S-R'), organic disulfides (R-S-S-R') and carbonyl sulfide (COS), from a hydrocarbon stream, the hydrocarbon stream containing one or more of said sulfur compounds is brought in contact with an absorbent containing a first transition metal sulfide in an absorption step in which at least some of the sulfur contained in the sulfur compound(s) is bound as additional sulfur in the transition metal sulfide such that a second transition metal sulfide is formed.
