Generalized Biomass to Ethanol Processes-details Enzymatic Hydrolysis - uses enzymes to cleave the carbon-oxygen-carbon link in cellulose molecule Acid Hydrolysis - uses acidic protons (H+) to cleave the carbon-oxygen-carbon link in cellulose molecule Strong, or Weak acid (i.e., concentrated, or dilute) Sulfuric, Hydrochloric, Nitric, Hydrofluoric, and so on. Combination of acid/enzymatic hydrolysis Structure of the cellulose molecule Site of attack by enzymes or acid 13
