Abstract


Hydrolysis reactions are of major importance to the oleochemical industry in the production of fatty acids and their derivates. During the hydrolysis of Castor oil using nickel catalysts it was verified that the glycerol produced worked as hydrogen donor, allowing the hydrogenation of unsaturated ester produced. Maximum conversion was achieved in 3 hours, using 25% NiO/CeO2/Al2O3 catalyst, temperature of 250°C and 280°C
