METHOD FOR DESULFURIZING OLEFIN-CONTAINING CHARGE MATERIAL BY CONTROLLING THE OLEFIN CONTENT

摘要

The invention relates to a process and a contrivance for carrying out the desulphurisation of a feed stream containing olefins and hydrogen. The latter may be mixed with additional hydrogen and is split into at least two feed streams. The first feed stream is introduced separately into the reactor and reaches a first catalyst bed which contains the catalyst pellets on a suitable supporting device or a grid. Here the feed stream is heated by the hydrogenation reaction. Downstream of the first catalyst bed further feed stream is supplied which will cool down the reaction gas which can then be passed through a second catalyst bed. Downstream of the second catalyst bed there may be further catalyst beds and further feed stream feed devices. The catalyst beds inside the reactor can be provided in any number  type and form desired...
