The carbonaceous materials are widely used as catalyst supports in different industrial reactions. The catalysts supported on activated carbon (AC) have advantages over other material: low cost, stability, mechanical strength, high surface area, ability to modify their surface chemistry, etc. Olefins obtained by hydrogenation of alkynes, are of great academic and industrial interest, either for the synthesis of biologically active compounds, in the production of margarine industry for lubricants, plastic, etc., also presenting fine chemical applications. The objectives of this work are: a) to prepare low loading palladium catalysts supported on activated carbon, using chloride and nitrate as precursor salts, and b) to evaluate them as catalyst during the liquid phase selective hydrogenation of 1-heptyne to 1-heptene.
