A size‐controlled palladium nanoparticle catalyst prepared by adsorption of colloidal palladium nanoparticles on barium sulfate is efficient and highly selective in transforming vegetable oils into diesel‐like fuel. Preliminary kinetic investigations using model compounds indicated that decarboxylation of aliphatic esters on palladium in a hydrogen‐rich atmosphere showed a zero‐order rate. Hydrogen temperature‐programmed desorption measurements revealed that the high‐temperature desorption of hydrogen species might be the rate‐determining step.
