Dispersed tiny bio-char particles in the raw bio-oil were removed by extraction using diethyl ether to suppress solid-particle-nucleated coking. Noble metal catalysts, instead of molybdenum-based catalysts, were selected to avoid the continuous addition of sulfur compounds. Among the catalysts, tungstate-zirconia-supported Ru catalysts (Ru/WZr) exhibited high hydrodeoxygenation activity and less formation of cokes, which characteristics are important in the development of feasible upgrading processes. The investigation of catalysts used in this study demonstrates that the larger quantity of Bronsted acid sites compared to Lewis acid sites suppresses the formation of cokes.
