✦ Synopsis

Preliminary process studies 011 the conversion of various biomass types into liquid fuels have indicated that HydroThermal Upgrading (HTU) is more attractive than pyrolysis or gasification. In HTIJ the biomass is treated at temperatures of 300-350 'C in the presence of liquid water for 5-15 min. A large proportion of the oxygen is removed as carbon dioxide. In a case study a process for the production of 3600 t/d hydrocarbons starting from wood is evaluated. Six HTU units convert wood into "biocrude" containing 10 %w oxygen. The biocrude is upgraded by catalytic hydrodeoxygenation in a central facility. The final products are kerosine and gas oil which may be expected to have excellent properties. The manufacturing cost is 400-450 S/t.
