Southeastern Regional Center Tennessee Agricultural Experiment Station The Cellulosic Ethanol Process 1. Preprocessing: Wood chips and switchgrass are delivered for storage, grinding, drying, and classification. 2. Pretreatment: A solvent fractionation process is used to separate the chemical components of the biomass (this step is specific to lignocellulosics). 3. Hydrolysis: Enzymes are used to break down the carbohydrates to their fermentable sugars (5C & 6C) 4. Fermentation & Distillation: Yeast converts the sugars to ethanol (or related alcohols), and water is removed to further concentrate the product.
