A method of removal of sulfur from a feed containing hydrogen sulphide and minimal traces of benzene; toluene and / or xylenes.

摘要

Procedure removal of sulfur from a feed containing hydrogen sulphide, sulfur dioxide, carbon oxysulphide and / or carbon sulphide and a minimal quantity of benzene, toluene and / or xylenes in at least one reaction zone containing a catalyst, and elemental sulfur and an effluent at least devoid of sulfur, which is used as catalyst at least one catalyst containing a support comprising at least one compound selected from the group formed by alumina, is recovered titanium oxide and zirconia, at least the support comprising further a compound selected from the group consisting of iron, cobalt, nickel, copper and vanadium dopant, in which the reaction zone comprises at least one bed containing the indicated catalyst located upstream of another catalytic mass as a protective layer of the said catalytic mass, the volume of the bed representing from 1 to 70% of volume reaction zone, and in which the catalytic mass is titanium oxide comprising a calcium salt, the mass disposed in the downstream part being.
