Abstract:
Partial hydrogenation of palm oil-derived biodiesel was investigated using supported palladium catalysts for improving the fuel properties, particularly oxidative stability (OS). In this work, three types of USY zeolites with different SiO2/Al2O3 ratios (USY(6.0), USY(14.9), and USY(810)) were used as supports for palladium catalysts to examine the influence of support acidity on the hydrogenation behavior. The catalysts were prepared by incipient wetness impregnation and characterized by N2 physisorption, TGA, TPR technique and CO-pulsed chemisorption. Support acidity was determined by NH3-TPD technique. It found that USY(6.0) exhibited the highest acidity, followed by USY(14.9) and USY(810) (1.127, 0.184 and 0.012 mmol/g, respectively). The partial hydrogenation was carried out in a continuous fixed-bed reactor under mild conditions of 85 degrees and 4 bars. The fatty acid methyl ester (FAME) compositions of the hydrotreated biodiesel were determined by GC. The results indicated that the catalysts effectively promoted the formation of more-saturated molecules. The catalytic activities of Pd/USY(14.9) and Pd/USY(810) catalyst were higher than that of Pd/USY(6.0). Due to the conversion of poly-unsaturated FAMEs to more-saturated FAMEs, the OS of hydrogenated biodiesel was significantly boosted up with a minor change of cloud point. The zeolite-supported palladiums have considerable potential as catalysts for partial hydrogenation to produce high-quality biodiesel with long-term stability.
