Patent ID: 8772427

Claim:
A modular biorefining process for separating a lignocellulosic feedstock into component parts and further processing of said component parts; the modular process comprising: a first processing module provided with a first series of steps for receiving, physically screening, and physico-chemically fractionating a lignocellulosic feedstock with an organic solvent separately provided thereto thereby extracting component parts therefrom, and separating said component parts into a first liquid fraction and a cellulosic solids fraction comprising a plurality of a first class of lignin derivatives therein; a second processing module provided with a second series of steps for receiving therein said cellulosic solids fraction and separating therefrom a sugar fraction; a third processing module provided with a third series of steps comprising: separating a first solids fraction from the first liquid fraction thereby producing a second liquid fraction, said first solids fraction comprising a plurality of a second class of lignin derivatives; separating a second solids fraction from the second liquid fraction thereby producing a third liquid fraction, said second solids fraction comprising a plurality of a third class of lignin derivatives; recovering from the third liquid fraction at least a portion of the organic solvent and a processed third liquid fraction; and a fourth processing module provided with at least one step for recovery of a first semi-solid waste material therefrom said processed third liquid fraction.
