1. Britney Blanchard Advisor: Dr. Junkun Ma ET 494 Final Presentation

2.  Main Goal: To produce ethanol from biomass in the most efficient and cost effective way.  Build and test a small prototype of the large scale biomass ethanol production plant that Southeastern wants to build on campus  Research the individual processes and their components to find the best combination to produce ethanol that is efficient and cost effective  Compile a materials list and build the prototype  Perform experiments and collect data to determine the best route.

3.  Pretreatment: Breaks Cellulose into Sugar  Fermentation: Turns Sugars to Ethanol  Distillation: Separates Ethanol from Mixture

6. Chemicals:  Sulfuric Acid  Tryptone  Sodium Chloride  Yeast Extract  Potassium Hydroxide Safety Equipment:  Lab Coat  Safety Goggles  Acid Resistant Gloves  Oven Gloves Equipment:  1000mL Beaker  Graduated Beaker Set  Graduated Cylinder Set  Thermometer  Glass Stir Rods  1000mL Distillation Kit  Hot Plate  Hot Plate Stirrer  Magnetic Stir Bar  (3)Lab Scoop  Glass trough  Glass Fiber Filter  Digital Scale  Electric Autoclave  Deionize Water Filter

7.  Material ordered  Some damaged

14. Pretreatment:  Mixture needs to be surrounded with heat when heating by using an oven or oven-like device  To make diluted sulfuric acid, be sure to add the acid to the water  Add as much grass as possible to the diluted acid, but be sure that all the grass is submerged Fermentation:  Autoclave the mixture to assure it is sterilized Distillation:  Setup needs to have a short path to assure the condensed liquid will travel to a separate container

15.  9-10 weeks: Multiple trial experiments performed, data collected, and improvements made to produce optimal process  3 weeks: Compile list of design specifications for the large scale production plant Now that the route runs smoothly, variables intend to check:  Time  Temperature  Chemical Concentrations
