| titleOfInvention | Processes and apparatus for lignin separation in biorefineries |
| abstract | The present invention generally provides methods of improving lignin separation during lignocellulosic biorefining, comprising the steps of (i) catalyzing fractionation or hydrolysis with an acid to release sugars into an acidified solution containing lignin, (ii) neutralizing the acidified solution with a base to form a salt in a neutralized solution; (iii) in a separation unit, separating the salt and the lignin, each in free or combined form, from the neutralized solution; and then (iv) recycling a portion of the salt and optionally a portion of the lignin to step (i) to combine, physically or chemically, with the lignin, to improve lignin separation in the separation unit. In certain embodiments, the acid is a sulfur-containing acid and the base is lime, forming gypsum which is then recycled, in part, to the hydrolysis reactor. |
