Further provided is a process that comprises feeding a concentrated still bottoms stream to a crystallizer and forming insoluble solids therein comprising salts. Furthermore, the invention relates to a process for recovering salts from a lignocellulosic conversion process, which process comprises the addition of solvent to a still bottoms stream to precipitate salts therefrom. Also provided is a still bottoms composition, a fertilizer product and a composition for incineration.

Abstract: Disclosed herein is a process for recycling water in a cellulosic conversion process that comprises selecting process stream(s) that may contain reduced levels of inhibitors and subsequently subjecting the stream(s) to a treatment process to produce treated water. The treated water is thereafter recycled to the cellulosic conversion process, associated utilities or the seal water system. The process streams selected for treatment may comprise less than 5 wt% organic content and/or less than 5 wt% inorganic content. The process of the invention comprises at segregating process streams based on their treatment requirements. The segregated process streams may be sent to respective separate treatments selected from anaerobic digestion, aerobic digestion, physical separation and chemical treatment.

Abstract: A method for recovering inorganic salt during processing of a lignocellulosic feedstock is provided. The method comprises pretreating the lignocellulosic feedstock by adding an acid to the feedstock to produce a pretreated lignocellulosic feedstock. A soluble base is then added to the pretreated lignocellulosic feedstock to adjust the pH and produce a neutralized feedstock. The neutralized feedstock is then enzymatically hydrolyzed to produce an enzyme hydrolyzed feedstock and a sugar stream. Inorganic salt is recovered from either a stream obtained from the lignocellulosic feedstock prior to the step of pretreating, a stream obtained from the pretreated lignocellulosic feedstock, a stream obtained from the neutralized feedstock, a stream obtained from the sugar stream, or a combination of these streams. The inorganic salt may be concentrated, clarified, recovered and purified by crystallization, electrodialysis drying, or agglomeration and granulation, and then used as desired, for example as a fertilizer.

Abstract: 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.
