WebMay 18, 2024 · Hydrogenation is a chemical reaction in which hydrogen atoms add to carbon-carbon multiple bonds. In order for the reaction to proceed at a practical rate, a catalyst is usually needed. Hydrogenation reactions are used in many industrial processes as well as in the research laboratory and occur in living systems. WebHydrogenation is an exothermic reaction, releasing about 25 kcal/mol in the hydrogenation of vegetable oils and fatty acids. For heterogenous catalysts, the Horiuti-Polanyi mechanism explains how hydrogenation occurs. First, the unsaturated bond binds to the catalyst, followed by H 2 dissociation into atomic hydrogen onto the catalyst.
