Methods and systems for fractionating lignocellulosic biomass including hemicellulose, cellulose and lignin, including exploding the biomass cells to devolatilize the biomass, hydrolyzing the hemicellulose to produce a liquid component including hemicellulosic sugars and a solid component including less than 10% hemicellulose, separating the liquid and solid components, vaporizing the cellulose in the solid component, and condensing the cellulosic sugar vapors. The methods and systems may vaporize the cellulose in a continuous steam reactor at a temperature of about 400-550° C. and a pressure of about 1-3 bara. Electromagnetic and/or electroacoustic treatment such as ultrasound and/or microwave treatment may be applied to the biomass immediately before or during cellulose hydrolysis.

대표청구항 ▼

1. A method of fractionating lignocellulosic biomass material comprising: feeding the biomass into a devolatilization reactor to remove volatile components of the biomass and obtain a prepared biomass;feeding the prepared biomass into a hemicellulose hydrolysis reactor to separate and hydrolyze hemicellulose;separating the biomass into a first solid component and a liquid component, wherein the liquid component includes hydrolyzed hemicellulose in water or solvent and wherein the first solid component includes cellulose and lignin and has less than about 10% hemicellulose;feeding the first solid component into a cellulose hydrolysis reactor comprising a continuous superheated steam reactor to hydrolyze and vaporize the cellulose component; andcondensing the vaporized cellulose. 2. The method of claim 1 wherein the cellulose hydrolysis reactor applies steam to the biomass at a temperature of at least 300° C. 3. The method of claim 1 wherein the cellulose hydrolysis reactor applies steam to the biomass at a temperature of between about 400 and 550° C. 4. The method of claim 1 wherein the cellulose hydrolysis reactor applies pressure to the biomass of 1-3 bara. 5. The method of claim 1 wherein the cellulose hydrolysis reactor applies steam to the biomass at a temperature of between about 400 and 550° C. and at a pressure of 1-3 bara. 6. The method of claim 1 wherein the cellulose hydrolysis reactor applies a mixture of steam and a gas to the first solid component. 7. The method of claim 1 wherein the gas comprises nitrogen, hydrogen, carbon dioxide, carbon monoxide, or combinations thereof. 8. The method of claim 1 further comprising applying electromagnetic or electroacoustic (EM/EA) treatment to the biomass. 9. The method claim 8 wherein the EM/EA treatment includes Pulsed Electric Field, ultrasonic energy, microwave energy, and combinations thereof. 10. The method of claim 1 further comprising applying ultrasonic energy to the biomass within the cellulose hydrolysis reactor. 11. The method of claim 1 further comprising applying microwave energy to the biomass within the cellulose hydrolysis reactor. 12. The method of claim 1 further comprising applying ultrasonic and microwave energy to the biomass within the cellulose hydrolysis reactor. 13. The method of claim 1 further comprising feeding the first solid component into a dryer comprising a continuous superheated steam reactor after separating the biomass in the hemicellulose hydrolysis reactor to reduce the water content of the first solid component before feeding the first solid component into the cellulose hydrolysis reactor. 14. The method of claim 1 further comprising attriting the first solid component after separating the biomass in the hemicellulose hydrolysis reactor and before feeding the first solid component into the cellulose hydrolysis reactor. 15. The method of claim 1 wherein the cellulose hydrolysis reactor produces a cellulose vapor and lignin char. 16. The method of claim 1 wherein the cellulose hydrolysis reactor hydrolyzes cellulose and produces a cellulosic sugar vapor and a second solid component. 17. The method of claim 16 further comprising feeding the second solid component into a second cellulose hydrolysis reactor comprising a superheated steam reactor. 18. The method of claim 17 wherein the first cellulose reactor partially hydrolyzes the cellulose and the second cellulose hydrolysis reactor completes cellulose hydrolysis and separates the vaporized cellulose from the lignin. 19. The method of claim 16 further comprising feeding the second solid component into a superheated steam reactor to reduce lignin to a condensable vapor.
