Abstract
A process to produce solid glucose from a hydrolyzate consisting of a mixture of glucose, water, and an acid used in the hydrolysis of a biomass material is covered herein. In the process, the hydrolyzate is concentrated, as required, to form two phases: a solid glucose phase and an acidic liquid phase. The phases are formed in a vessel where they are separated for recovery of the acidic liquid phase. The solid glucose phase, containing residual acidic liquid phase, is then extracted to remove most of the residual acid to produce solid glucose mostly free of acid. The recovered acid may then be recycled. The solid glucose may be further processed including purification and also drying.
Claims21
A process for producing solid glucose from an aqueous solution including a mixture of glucose and an acid;
- said solution being capable of forming two phases, which comprises:
- providing a vessel in which a solid glucose phase and an acidic liquid phase are formed;
- separating means for parting the solid glucose phase and the acidic liquid phase;
- and
- extracting means for freeing most of any residual acid from the solid glucose, thereby providing nearly acid free solid glucose.
