摘要： In a process for recovering acetic acid from a wood extract, an aqueous wood extract is provided that contains acetic acid and dissolved hemicellulose containing uronic acid. A water insoluble solvent containing an extractant for the acetic acid is also provided. In a preferred embodiment, the solvent is undecane and the extractant is trioctylphosphine oxide. The wood extract is contacted with the solvent and extractant in order to extract the acetic acid from the wood extract. The acetic acid is then recovered from the solvent and extractant.

摘要： A process for upgrading an organic acid includes neutralizing the organic acid to form a salt and thermally decomposing the resulting salt to form an energy densified product. In certain embodiments, the organic acid is levulinic acid. The process may further include upgrading the energy densified product by conversion to alcohol and subsequent dehydration.

摘要： A method for the fractionation of lignocellulosic materials into cellulose, hemicelluloses and lignin in a batch or continuous process in a treatment with vaporous mixture of aliphatic alcohol, sulfur dioxide and water. Cooking conditions are varied to get different proportions of cellulose, hemicelluloses and lignin. Chemical recovery through pressure release is described.

摘要： The present invention relates to producing chemicals and biofuels from wood material, e.g. mixed forest biomass. Specifically, the invention concerns a process for conditioning spent liquor produced by SO2-ethanol-water (SEW) fractionation of wood chips for fermentation to butanol, ethanol and acetone/isopropanol (so called ABE process) by Clostridia bacteria.
