Techno-Economic Assessment of Selected Biomass Liquefaction Processes

摘要

A techno-economic assessment was carried out as part of the International Energy Agency (IEA) Biomass Agreement. The overall objective of the work was to identify the optimum process concept to be considered for testing in a possible international test facility. The participating countries were Canada, Finland, Sweden, and the United States. The comparison of the processes was primarily based on estimated production costs of synthetic gasoline. Processes were also assessed based on their technical merits, and the availability of experimental data was one of the prime criteria for the selection of analyzed process concepts. In an earlier study by IEA it was shown that atmospheric flash pyrolysis and high pressure liquefaction are the preferred direct liquefaction concepts for the production of fuel oil substitutes from biomass.
