Presentation Transcript

  1. Discussion • A one-way ANOVA followed by a Scheffe post-hoc test revealed no significant difference between any groups in the volume of raw biodiesel produced (p<.1) • The enzyme and acid group were significantly different from the basic group in regard to the concentration of impurities found • Even though the enzyme catalyst produced greater amount of purer biodiesel, the acid catalyst was more efficient because it produced more pure biodiesel at a lower cost Picture 8: Purity of the biodiesel was measured via titration (Photo by Author) Limitations • Some challenges faced in this experiment were finding a way to accurately collect data, extracting algae oil, and measuring pH accurately because biodiesel is not very conductive Conclusion Picture 9: Algae being grown in the laboratory setup at room temp. and regular fluorescent lights (Photo by Author) • The acid catalyst was the most cost efficient choice for biodiesel production • The acid catalyst can be reused several times and is almost as inexpensive per gram as sodium hydroxide • The study is similar to results of other researchers, acid and enzyme catalysts were both more efficient than the base Future Studies • Running the trial using other types of acid or enzyme catalysts • Determining the energy content of the biodiesel • Using different alcohol and different types of algae • Using Le Chatlier’s principles to favor the forward reaction to biodiesel more Bibliography "Biofuel Development Shifting From Soil to Sea, Specifically to Marine Algae."
