FIELD: petrochemical process catalysts.
SUBSTANCE: reaction gas is passed in reaction zone through at least one fixed catalyst bed wherein reaction gas is subjected to dehydrogenation to produce molecular hydrogen and at least one dehydrogenated hydrocarbon. Reaction gas, before and/or after entering reaction zone, is supplemented by at least one molecular oxygen-containing gas, which partially oxidizes molecular hydrogen contained in reaction gas to form water steam. Gas product containing molecular hydrogen, water steam, at least one dehydrogenated hydrocarbon, and at least one hydrocarbon to be dehydrogenated is withdrawn from reaction zone, and divided into two parts, one of which is recycled into reaction zone.
EFFECT: simplified process and increased propylene formation selectivity.
