摘要：
Recent progress in biomass fast pyrolysis technology for bio-oil production is briefly reviewed. The chemical composition and fuel properties of bio-oil are described. Bio-oil is a complex mixture of water and oxygenated compounds. It possesses many unique properties and characterized as high in water and oxygen content, low in caloric value, acidic and corrosive to common metal materials, chemically and thermally unstable, and non-miscible with petroleum fuels. Bio-oil has to be upgraded before it can be used as high-grade liquid fuels. Some upgrading methods relatively well developed are discussed, which include catalytic cracking, catalytic hydrotreatment, hot vapor filtration, solvent addition, catalytic esterification, emulsification with diesel, as well as production of hydrogen-rich syngas for Fisher-Tropsch synthesis. The key problems involved in these upgrading methods are also discussed.
