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

Publication number: 20120202260Abstract: Processes and systems for concurrent recovery of lignin derivatives and syngas from a lignocellulosic feedstock. The processes and systems therefor generally comprise the steps of: (a) perfusing and cooking the lignocellulosic feedstock with a suitable organic solvent for a suitable period of time thereby producing a cellulosic solids output stream and a spent liquid solvent stream, said spent liquid solvent stream comprising solubilized lignin derivatives and other organic compounds; (b) separating said cellulosic solids output stream and said spent liquid solvent stream; (c) recovering lignin derivatives from the spent liquid solvent stream thereby producing at least a partially de-lignified spent liquid solvent stream; (d) recovering a portion of the organic solvent from the at least partially de-lignified spent liquid solvent stream thereby producing a stillage; and (e) gasifying the cellulosic solids output stream thereby producing a combustible syngas.Type: ApplicationFiled: September 3, 2010Publication date: August 9, 2012Applicant: LIGNOL INNOVATIONS LTD.Inventor: John Ross Maclachlan

Patent number: 8193324Abstract: 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: November 26, 2008Date of Patent: June 5, 2012Assignee: Lignol Innovations Ltd.Inventors: Christer Hallberg, Donald O'Connor, Michael Rushton, Edward Kendall Pye, Gordon Gjennstad, Alex Berlin, John Ross MacLachlan, Raymond Ma

Publication number: 20120094348Abstract: An apparatus for processing sugar cane to concurrently produce sugar from cane juice, and ethanol and other co-products from bagasse. The apparatus comprises equipment for separating a cane juice stream and a fibrous bagasse from a sugar cane feed-stock, equipment for refining the cane juice, equipment for processing the fibrous bagasse for recovery therefrom of a cellulosic pulp and a liquor stream, equipment for saccharification and fermentation of the cellulosic pulp to produce a fermentation beer therefrom, and equipment for recovery of an ethanol stream from the fermentation beer. Legacy sugar mills may be retrofitted with a bagasse biorefining apparatus to concurrently produce ethanol and co-products, with existing cane juice extraction and processing operations.Type: ApplicationFiled: January 15, 2010Publication date: April 19, 2012Inventors: Edward Kendall Pye, Michael Rushton, John Ross Maclachlan

Publication number: 20110236946Abstract: A process for concurrent production of lignins, fuel alcohol, and biogas from lignocellulosic feedstocks. The process comprises: (1) pretreating a lignocellulosic feedstock to produce a solubilised liquid components stream comprising lignins, lignin-derived compounds, and a cellulosic pulp stream, (2) separating the liquid stream from the cellulosic pulp stream, (3) processing the liquid stream to separate and recover at least lignins, lignin-derived compounds, and semi-solid waste material, (b) processing the cellulosic pulp stream to saccharify and ferment the cellulose pulp to produce a beer which is then separated into fuel-grade alcohol and a waste stillage material, (4) anaerobically digesting the semi-solid waste material from the liquid stream and the waste stillage material to produce a biogas. The rate of anaerobic digestion can be manipulated by controllably supplying a portion of the monosaccharides produced from the cellulosic pulp. The cellulosic pulp stream may also be anaerobically digested.Type: ApplicationFiled: May 23, 2008Publication date: September 29, 2011Applicant: LIGNOL INNOVATIONS LTD.Inventors: John Ross Maclachlan, Edward Kendall Pye
