Publikováno v: Reaction Kinetics, Mechanisms and Catalysis. 127:259-281
Low loaded W-Pd/Alumina are relatively novel catalysts for performing the selective hydrogenation of alkynes, but there is scarce information on the working mechanism. This work studies the kinetics of the selective hydrogenation of 3-hexyne to (Z)-3
