Patent number: 8772427Abstract: A modular process for organosolv fractionation of lignocellulosic feedstocks into component parts and further processing of said component parts into one or more of a de-lignified cellulose stream, a sugar stream, small-chain alcohol streams and four structurally distinct classes of lignin derivatives. The modular process comprises a first processing module configured for digesting lignocellulosic feedstocks with an organic solvent thereby producing a cellulosic solids fraction and a liquid fraction, a second processing module configured for recovering small-chain alcohols and optionally a first class of lignin derivatives from the cellulosic solids fraction, a third processing module configured for recovering from the liquid fraction at least one of a second class and a third class of lignin derivatives or mixtures thereof, and waste stream comprising a fourth class of lignin derivatives. The fourth processing module may optionally recover the fourth class of lignin derivatives.Type: GrantFiled: May 30, 2012Date of Patent: July 8, 2014Assignee: Lignol Innovations Ltd.Inventors: Christer Hallberg, Donald O'Connor, Michael Rushton, Edward Kendall Pye, Gordon Gjennstad, Alex Berlin, John Ross McLachlan, Raymond Ma

Patent number: 8528463Abstract: A modular process for organosolv fractionation of lignocellulosic feedstocks into component parts and further processing of said component parts into at least fuel-grade ethanol and four classes of lignin derivatives. The modular process includes a first processing module configured for physico-chemically digesting lignocellulosic feedstocks with an organic solvent thereby producing a cellulosic solids fraction and a liquid fraction, a second processing module configured for producing at least a fuel-grade ethanol and a first class of novel lignin derivatives from the cellulosic solids fraction, a third processing module configured for separating a second class and a third class of lignin derivatives from the liquid fraction and further processing the liquid fraction to produce a distillate and a stillage, a fourth processing module configured for separating a fourth class of lignin derivatives from the stillage and further processing the stillage to produce a sugar syrup.Type: GrantFiled: July 23, 2012Date of Patent: September 10, 2013Assignee: Lignol Innovations Ltd.Inventors: Christer Hallberg, Donald O'Connor, Michael Rushton, Edward Kendall Pye, Gordon Gjennestad, Alex Berlin, John Ross MacLachlan
