ABSTRACT:
A process for desulfurising an olefin-containing hydrocarbon feedstock including sulfur-containing hydrocarbon compounds as impurities, the process comprising passing a hydrocarbon feedstock containing one or more olefins through a reactor containing a crystalline silicate selected from the group consisting of an MFI-type crystalline silicate having a silicon/aluminum atomic ratio of at least 180 and an MEL-type crystalline silicate having a silicon/aluminum atomic ratio of from 150 to 800 which has been subjected to a steaming step to produce an effluent with an olefin content of lower molecular weight than that of the feedstock and removing hydrogen sulphide from the effluent.
