Abstract
Methods are disclosed for providing recovered lignin of suitable quantity and quality to provide sufficient heating value to power the generation of supercritical or near critical water without the need for outside sources of energy. Supercritical or near critical water generator devices and systems are also disclosed.
Claims9
A system for generating supercritical or near critical water, comprising:
- a biomass conversion system adapted to produce lignin from a material comprising lignocellulose using supercritical or near critical water;
- a supercritical or near critical water generator adapted to provide supercritical or near critical water to said biomass conversion system, said supercritical or near critical water generator comprising:
- at least one pump adapted to provide water at a pressure of at least about 221 bar to form compressed water;
- and
- at least one fuel combustion apparatus adapted for combusting a fuel composition comprising said lignin;
- wherein said lignin has a heating value of at least about 3,000 BTU/lb;
- a fuel handling system adapted to transport said lignin from said biomass conversion system to said fuel combustion apparatus;
- and
- a water circulation system adapted to transport said compressed water in proximity of said fuel combustion apparatus adequate to heat said compressed water to a temperature of at least about 373° C. to produce said supercritical or near critical water.
