Abstract (en)

[origin: WO0048970A1] A method of improving the operation of a process system used for conversion of C2-C6 alkynes (preferably acetylene) contained in a hydrocarbon-containing fluid with hydrogen to the corresponding alkenes. The process system, before improvement, utilizes a volumetric amount of a hydrogenation catalyst required for providing conversion of the C2-C6 alkynes to a conversion product containing less alkynes than the hydrocarbon-containing fluid. The method of improvement involves contacting, in a single-stage adiabatic reaction zone, under reaction conditions, the hydrocarbon-containing fluid containing C2-C6 alkynes (preferably acetylene) with a catalyst containing palladium, silver, and an alkali metal compound (preferably an alkali metal fluoride) in a conversion-improving volumetric amount that is less than the volumetric amount of hydrogenation catalyst.
