Summary: | A process and a device for the hydrodesulphurisation of an olefin and hydrogen-containing feed gas utilizes a feed gas which can be mixed with further hydrogen and subdivided into at least two feed streams. The first feed stream is introduced separately into the reactor and is passed through a first catalyst bed which contains the catalyst pellets deposited on a suitable support or grid. The feed stream is heated in the hydrogenation reaction. Downstream of first catalyst bed, further feed gas is supplied which serves to cool the reaction gas permitting that the gas can then be passed through a second catalyst bed. Downstream of the second catalyst bed there may be further catalyst beds and further feed gas supply devices. The catalyst beds can be provided in the reactor in any number, type and shape. These process conditions ensure that a product gas be obtained which essentially contains no other sulphur compound than hydrogen sulphide. |
