Abstract: A method for autothermal or substantially autothermal catalytic dehydrogenation of hydrocarbons is described. A hydrocarbon containing feed gas is optionally mixed with steam and/or hydrogen, is pre-heated and is introduced into a catalytic bed of a reactor, where an oxygen containing gas is fed directly into the catalytic bed from one or more oxygen supply tube(s) (3) each tube (3) having one or more opening(s) distributed in the catalytic bed.
