ABSTRACT:

Finland's self-sufficiency in liquid fuels and certain chemicals can be increased by producing these liquids from indigenous solid fuels. Research on liquefaction in Finland has at present two aims: the first, a short-term objective, is to prove the technical feasibility of peat and/or wood conversion at commercial scale, and the second, a long-term objective is to participate in the development of new, more effective conversion processes. In this study the production of ammonia, methanol, ethanol and liquid fuels is primarily considered. The processes based on synthesis gas are closest to commercialization, but especially certain pyrolysis and high-pressure hydrogenation methods (direct liqufaction) under development seem to be promising, for example, due to their high efficiency. The most economic method of producing gasoline from peat or wood is to convert the methanol produced from these materials to gasoline via a Methanol-to-Gasoline process. It is expensive to produce diesel oil by the Fischer-Tropsch synthesis. The development of a direct peat liquefaction process may lead to a more favourable alternative than those mentioned above.
