摘要：

Hydrodeoxygenation (HDO) of pyrolysis bio-oil produced from cork oak was carried out in supercritical ethanol. Three typical HDO catalysts Pt/Al2O3, Ni/HY, and Pd/Carbon were used. In order to compare the characteristics of raw bio-oil and catalytically reformed HDO oil, the measurement of pH, water content, and viscosity as well as elemental and composition analyses were conducted. The aging assessment based on acids content and higher heating value was performed to evaluate the stability of oils as fuel. The order of stability of the HDO oils was Pt/Al2O3 > Pd/Carbon > Ni/HY. In particular, the HDO oil obtained using Al2O3 catalyst was affected little by aging.
