Catalytic activity of titania supported palladium, which was prepared by means of the incipient wetness impregnation, for hydrocracking of oleic acid was investigated in order to study production of liquid hydrocarbon from vegetable oil. The catalytic hydrocracking of oleic acid was carried out at the temperature ranging from 290°C to 350°C under the initial hydrogen pressure of 2 MPa. A major product of the catalytic hydrocracking was heptadecane, and a small amount of octadecane was produced through the deoxygenation pathway. An amount of carbon dioxide produced from the oleic acid indicated that the decarbonylation pathway was prior to the decarboxylation one for the conversion into heptadecane. At 350°C, oleic acid or its hydrogenated derivative seemed to be dimerized into the major by-product.
