The aim of this report is to review research on biomass liquefaction, different conversion methods and their stage of development. Production costs related to different methods are compared with each other to evaluate development possibilities and to direct the research accordingly. The research on biomass conversion is a part of the development work whereat alternatives are sought for to replace products based on raw oil. The development work done at the Technical Research Centre of Finland (VTT) and international co-operation, in which Finland has participated, are briefly reviewed. Different liquefaction methods are presented with the aid of examples. Alternative raw materials are listed briefly. The supply of liquid fuels in a crisis and alternatives of synthetic liquid fuel production are evaluated. In addition to rationing, the only way of securing the liquid fuel supply is to change an existing production plant to produce liquid fuels. Possible production alternatives are presented. Production cost estimates for substitude liquid fuels are presented to facilitate the comparison of different process concepts. The production costs of the liquid fuels produced from peat and wood would be about 1.5-2.5-fold compared to those of the reference oil products (mid-1985). Finally, the need for research is evaluated. Both the production of synthesis gas from wood and the hydrogenation of black liquor should be studied because of the significant production potential of industrial applications. The purification of the synthesis gas produced from biomass is another important object of research. The upgrading of primary oils produced from biomass is of crucial significance when aiming at improving the profitability of the biomass-derived liquid fuels.
