Abstract

A one-pot catalytic hydrolysis–deoxygenation reaction for the conversion of unsaturated triglycerides and free fatty acids to linear paraffins and olefins is reported. The hydrothermal deoxygenation reactions are performed in hot compressed water at 250¿°C over a Pd/C catalyst in the absence of external H2. We show that aqueous–phase reforming (APR) of glycerol and subsequent water–gas-shift reaction result in the in situ formation of H2. While this has a significant positive effect on the deoxygenation activity, the product selectivity towards high-value, long-chain olefins remains high.
