Claims28
A method for the preparation of a cellulose-containing composition comprising the steps of:
- (a) forming a first slurry comprising a cellulose-containing feedstock, water, and acid;
- (b) subjecting the first slurry to rapid heating to a first temperature, by addition of subcritical, near critical or supercritical water, at a first pressure, thereby forming a second slurry;
- (c) maintaining the second slurry at the first temperature and first pressure for a first time period;
- (d) rapidly depressurizing the second slurry to form a third slurry at a second temperature and a second pressure;
- and
- (e) separating the liquid portion from the solid portion of the third slurry, the solid portion of which comprises the cellulose-containing composition;
- wherein the first temperature is in the range of 180° C. to 280° C.;
- and
- wherein the cellulose contained in the cellulose-containing composition has a weight average molecular weight between 40,000 grams/mole and 155,000 grams/mole.
