catalytic conversion of pyrolytic vapors of woody biomass

Résumé

Fast pyrolysis of biomass yields bio-oils with high levels of oxygen containing components and high acidity and little stability. Further upgrading of these oils is necessary before they can be processed into liquid fuels. Several low-cost strategies have been proposed for reducing the oxygen and acid content. Catalytic pyrolysis consist of utilizing a catalyst during the pyrolysis or by directly processing the pyrolysis gas over a catalyst. In the present work, we have designed a lab-scale reactor for fast catalytic pyrolysis of wood chips. Recovery of the bio oils fractions, gases, chars leads to a mass balance higher than 95%. Liquid yields are in the of 50-55 % range. A screening of acidic catalysts (zeolites, silica alumina) has been performed. Characterization of liquids and solids was performed.
