Solid acid catalyzed biodiesel production by simultaneous esterification and transesterification Screening of supported TPA for biodiesel production from canola oil. Reaction conditions: reaction temperature 200 °C, molar ratio of oil to alcohol 1 : 6, stirring speed 600 rpm, catalyst loading 3% w/w. Kulkarni et. Al 2006

Enzymatic production of biodiesel from cotton seed oil using t-butanol as a solvent Fig. 1. Effect of t-butanol on oil conversion during the enzymatic methanolysis of cotton seed oil, using a discontinuous system with a 6:1 methanol to oil molar ratio. Reactions were performed at 50 °C with 18 g of oil and 300mg enzyme; vol% of t-butanol in the mixture: 32.5% (□), 26.5% (◊), 19% (○), 11% (∆), 0% (*). Royon et. Al 2006

Cultured High Oil Yield Algae Centrifuged to Remove Water Used for the Base CatalystUsed for the Acid Catalyst Used for the Enzyme Catalyst Base catalyst will be added as a solid until dissolved Acid synthesized from hydrated zirconia and 12- TPA Enzyme added from Novozymes Methanol, Algae samples, and catalyst for each group are put into a beaker for the reaction to occur Reaction will take place in an oven at 60 º C for 10 hours Reaction will take place on a hot plate at 60 º C for 10 hours Reaction will take place at 60 º C on a hot plate for 10 hours Amount of biodiesel produced will be measured and the amount of energy it produces will be collected through combustion Synthesis of Biodiesel Using Acid, Base, and Enzyme Catalysts

Do-Ability Enzyme from Novozymes Sodium Hydroxide 12-TPA and Hydrated Zirconia Centrifuge for algae extraction Algae cultures Hot Plate Oven

Hypotheses 1(a) Biodiesel produced by the base will be significantly more effective than the other catalysts 2(a) Biodiesel produced by the acid will be significantly more effective than the other catalysts 3(a) Biodiesel produced by the enzyme will be significantly more effective than the other catalysts

Purpose The purpose of this experiment is to determine the effectiveness of acid, base, and enzyme catalysts when the oil is produced from the same algal culture
