摘要： A process for recovering a volatile carboxylic acid from an aqueous stream comprising same, the process comprising the steps of: (i) steam stripping the carboxylic acid from the aqueous stream, which aqueous stream is produced by a conversion process using a lignocellulosic feedstock as a substrate, the steam stripping comprising contacting the aqueous stream with steam by flowing the aqueous stream and the steam countercurrent to one another, thereby producing a vapour stream comprising vapourized carboxylic acid and steam and a stripped aqueous stream; (ii) extracting the vapourized carboxylic acid with an organic solvent by contacting the vapour stream with the organic solvent to produce (a) a stream comprising the organic solvent and the carboxylic acid and (b) the steam at least substantially depleted of the carboxylic acid, wherein the organic solvent has an atmospheric boiling point of at least about 150°C and is insoluble in water; (iii) returning the steam from step (ii) to the steam stripping step (step i) to further strip the carboxylic acid from the aqueous stream; and (iv) separating the carboxylic acid from the organic solvent.

摘要： A process for the enzymatic hydrolysis of cellulose to produce a hydrolysis product from a pretreated cellulosic feedstock is provided. The process comprises introducing an aqueous slurry of the pre-treated cellulosic feedstock at the bottom of a hydrolysis reactor. Axial dispersion in the reactor is limited by avoiding mixing and maintaining an average slurry flow velocity of about 0.1 to about 20 feet per hour, such that the undissolved solids flow upward at a rate slower than that of the liquid. Cellulase enzymes are added to the aqueous slurry before or during the step of introducing. An aqueous stream comprising hydrolysis product and unhydrolyzed solids is removed from the hydrolysis reactor. Also provided are enzyme compositions which comprise cellulase enzymes and flocculents for use in the process. In addition, a kit comprising cellulase enzymes and flocculent is provided.

摘要： The present invention pertains to a method of converting cellulose to glucose by treating a pretreated lignocellulosic substrate with an enzyme mixture comprising cellulase enzyme and a modified CBHI, wherein the modified CBHI is present in the enzyme mixture at an amount relative to all CBHI-type enzymes from about 15% to about 100% (w/w), dpending upon the modified CBH1 used. The pretreated lignocellulosic substrate is selected from the group consisting of agricultural residues, residues after starch or sugar removal, dedicated ethanol crops, forestry products, and pulp and paper products, or combinations thereof.
