The catalytic partial hydrogenation of acetylenes has been widely studied in the last years due to its academic and industrial interest. Products obtained from these reactions are useful in the synthesis of fine chemicals and biological active compounds. In a recent work we found that low loaded W and Pd bimetallic catalysts proved to be very active and selective for the partial hydrogenation of a long chain terminal alkyne, 1-heptyne. The objective of this work is to study the behavior of the bimetallic catalyst WPd/Al2O3 during the semi-hydrogenation of 4-octyne, a long chain non terminal alkyne.
