摘要: The metal-acid bifunctional catalysts have been used for bio-oil upgrading and pyrolytic lignin hydrocracking. In this work, the effects of catalyst properties, including acidity, pore size supported metal on hydrocracking in supercritical ethanol hydrogen were investigated at 260 °C. A series prepared characterized by BET, XRD, NH3-TPD techniques. results showed that enhancing acidity without can promote polymerization to form more solid condensation produce water. microporous was smaller than mesoporous catalyst. Together with strong it caused further hydrocrack numerous gas. Introducing Ru into acidic promoted inhibited condensation, which yield liquefaction product increase significantly. Therefore, high activity materials sites mesopores imperative get satisfactory conversion liquid products under conditions atmosphere.
