PROCESS FOR THE DEHYDROGENATION OF HYDROCARBONS

摘要

An improvement is provided in a process for the dehydration of a hydrocarb on feed stream. That process includes the steps of contacting the feed stream with a dehydrogenation catalyst in at least one dehydrogenation zone and reacting t he feed stream to produce a hydrogen-containing effluent stream into the effluent stream. An oxygen-containing atmosphere is admixed in at least one mixing zone. Hydroge n is removed from the effluent stream by reaction with oxygen in the oxygen- containing atmosphere by contact with a hydrogen oxidation catalyst in at least one hydrogen removal zone. The improvement comprises employing unsupported forms of noble metals or alloys thereof as catalyst in the at least one hydrogen removal zone.
