This paper is based on the results of a technoeconomic assessment of direct biomass liquefaction processes converting wood and peat to gasoline and diesel fuels. The assessment was carried out by the Working Group of the International Energy Agency, Direct Biomass Liquefaction Activity, in which Canada, Finland, Sweden, and the United States participated. The processes chosen for detailed analysis were Atmospheric Flash Pyrolysis (AFP) and Liquefaction In Pressurized Solvent (LIPS). The assessment covered three steps for each process from feed to final product: primary liquefaction to a crude oil product; catalytic hydrotreating to upgrade the crude product to a deoxygenated product oil; and refining the deoxygenated product to gasoline and diesel fuel. Present technology cases and potential future technology cases were evaluated. A consistent analytical basis was used throughout to allow comparison of the processes. This assessment shows that AFP is more economical than LIPS both for the production of boiler fuel oil as the primary liquefaction product and for the production of gasoline and diesel fuel products. The potential for future cost reduction through research and development is also clearly demonstrated. 23 refs., 14 figs., 7 tabs.
