Abstract: It is disclosed an integrated process for producing at least a cellulosic pulp comprising cellulose in the form of fibers and a polyols stream from a ligno-cellulosic feedstock comprising cellulose, hemicellulose and lignin. The process comprises the steps of: a) Treating the ligno-cellulosic feedstock to produce the cellulosic pulp and at least a liquid sugar stream comprising water and monomeric sugars derived from the hemicellulose of the ligno-cellulosic feedstock; b) Catalytically converting the monomeric sugars of the liquid sugar stream to a polyols mixture, comprising primary polyols and secondary polyols; c) Separating at least a portion of the polyols mixture into at least the polyols stream and a residual stream, wherein the polyols stream comprises the majority by weight of the primary polyols and the residual stream comprises the majority by weight of the secondary polyols; d) Recovering a first thermal energy from the residual stream in a first recovery unit.

Abstract: The process for the treatment of ligno-cellulosic biomass comprises the steps of: A) Soaking a ligno-cellulosic biomass feedstock in vapor or liquid water or mixture thereof in the temperature range of 100 to 210° C. for 1 minute to 24 hours to create a soaked biomass containing a dry content and a first liquid; B) Separating at least a portion of the first liquid from the soaked biomass to create a first liquid stream and a first solid stream; wherein the first solid stream comprises the soaked biomass; and C) Steam exploding the first solid stream to create a steam exploded stream comprising solids and a second liquid.

Abstract: It is disclosed a process for removing at least a portion of the furfural and acetic acid in a first stream comprised of water, at least one compound selected from the group consisting of furfural and acetic acid, C5's and C6's. Such process comprises the steps of contacting the stream with an adsorption media which has been previously contacted with a second stream comprised of the same components and the adsorption media has been regenerated by exposing it to conditions, without being in contact with the second stream, such that at least 70% of the adsorbed furfural and acetic acid have each been desorbed and at least 60% of the C5's and C6's remain adsorbed on the media.
