Process for producing hydrocarbon-containing liquids from biomass which comprises introducing biomass in the presence of water at a pressure higher than the partial vapor pressure of water at the prevailing temperature into a reaction zone at a temperature of at least 300 DEG C. and keeping the biomass in the reaction zone for more than 30 seconds, separating solids from fluid leaving the reaction zone while maintaining the remaining fluid in a single phase, and subsequently separating liquids from the remaining fluid. |
