CHAPTER 9: BIOCHEMICAL PROCESSING OF CARBOHYDRATE-RICH BIOMASS
Bio-chemical
Aerobic digestion
Anaerobic digestion
Fermentation
Carbohydrate rich biomass
Starch
Sugar
Fermentation
Ethanol (product)
Types
:
Ethanol Fermentation
Sugars & starch fermentation
Acetone-butanol fermentation
Lactic acid fermentation
Hydrogen fermentation
Enzymes convert starch to sugar
Yeast convert sugar to ethanol
Distillation
Purification of ethanol
Energy-intensive step
Hydrothermal processing (HTP)
Processing in hot water, compressed liquid water/supercritical water.
Pressure & temperature product
CHO from HTP
: 200oC & 20 bar. (CHO hydrolyzed to fermentable sugars
Biocrude frm HTP
: 300oC & 150 bar (production diesel fuel)
Syngas frm HTP
: 600oC & 230 bar (H, CO, CH4)
Hybrid thermo/bio-chemical refinery
Bio-oil
Syngas
