- Abstract
The partial hydrogenation of jatropha-oil-derived biodiesel fuel (BDF) with a high degree of unsaturated fatty acid tails was successfully performed on an alumina-supported palladium catalyst, denoted Pd/γ-Al2O3, under mild conditions (100 °C and 0.5 MPa) to produce hydrotreated fatty acid methyl esters (H-FAMEs) enriched in monounsaturated components. Trace amounts of peroxides contained in the oil feedstock or the cofeeding of proper amounts of molecular oxygen (400-1500 ppm) resulted in enhanced activity and durability of Pd/γ-Al2O3. The produced H-FAMEs exhibited significantly improved oxidation stability and uncompromised cold-flow properties, and they can serve as an excellent source of high-quality BDFs, particularly for high-blend fuels.
