Abstract: In a process for hydrotreatment of a gas stream containing both olefins and diolefins as well as organic sulfur compounds, the gas stream is introduced into a pre-treatment reactor, where diolefins are reacted with hydrogen in the presence of a supported Mo-catalyst not containing Co or Ni, whereby the diolefins are substantially converted to olefins. Then the gas stream is introduced into a hydrotreater reactor having a higher inlet temperature than the pre-treatment reactor, in which the gas stream is reacted with hydrogen in the presence of a hydrotreating catalyst under hydrodesulfurisation process conditions, whereby the olefins are substantially converted to paraffins and the organic sulfur compounds are converted to H2S, which is removed by subjecting the hydrotreated gas to a chemisorption or physisorption treatment.
