Two catalysts based in palladium on CaCO3 were compared and evaluated during the selective hydrogenation of 1-heptyne. One of them was synthetized in the laboratory from an amino complex solution of palladium and deposited on the support by incipient wetness technique. Another them is the Lindlar commercial catalyst. A low loaded Pd/CaCO3 catalyst was prepared from an amino complex. The synthesized catalyst presented higher initial reaction rate than the commercial Lindlar catalyst with higher selectivity to 1-heptene, 90 %. Higher activity of the prepared catalyst might be related to a higher dispersion.
