First Claim
Patent Images
1. Process for a controlled conversion of a biomass feedstock, wherein the process comprises:
- loading the biomass feedstock to at least one reactor;
liquefaction of the biomass feedstock into a monomer and/or oligomer sugar mixture in said reactor by treatment in hot compressed liquid water at sub- and/or supercritical condition; and
removal of the monomer and/or oligomer sugar mixture to avoid continued detrimental decomposition;
and wherein the liquefaction is performed at a temperature of at least 280°
C. during a reaction time t of from 1.5 to 30 s.

Abstract
The present invention describes a process for a controlled conversion of a biomass feedstock, wherein the process comprises the steps of:
- loading the biomass feedstock to at least one reactor;
- liquefaction of the biomass feedstock into a monomer and/or oligomer sugar mixture in said reactor by treatment in hot compressed liquid water (HCW) at sub- and/or super-critical condition; and
- removal of the monomer and/or oligomer sugar mixture, being the product molecules, to avoid continued detrimental decomposition.
