Abstract: Production of alkenes by liquid-phase hydrogenation of alkynes containing 10-30 carbon (C) atoms comprises using a monolithic supported palladium catalyst and hydrogen containing 10-2000 ppm carbon monoxide (CO). Production of alkenes by liquid-phase hydrogenation of alkynes containing 10-30 C atoms at 20-250 degrees C and a hydrogen partial pressure of 0.3-200 bar comprises: (a) using a fixed bed of a catalyst prepared by calcining a support material in air, cooling it, impregnating it with a solution containing a palladium salt and optionally other metal ions, drying the product and shaping it into a monolithic catalyst element; and (b) either adding 10-2000 ppm CO to the hydrogen or generating an equivalent amount of CO by adding a CO-releasing compound to the liquid phase.
