FIELD: dehydrogenation catalysts. SUBSTANCE: catalyst based on Cu/Zn/Al and/or Cr oxide system promoted by alkali metals is prepared by way of coprecipitation from salt solution by alkali metal carbonate solution and subsequent heat treatment. Alkali metal is introduced into catalyst in the stage of precipitation involving incomplete washing of precipitate from alkali metal ion. EFFECT: improved preparation procedure.
