ABSTRACT:
Supercritical and near critical fluids are used to fractionate biomass materials in two steps. In the first step, the biomass is exposed to elevated pressure supercritical or near critical fluid to bring about disruption of the biomass. In the second step, the disrupted biomass is subjected to a multiplicity of supercritical or near critical fluid extraction steps, with different solvation conditions used for each fraction. Thus, fractionation of the biomass is effected.
