Discussion
•Data shows that the enzyme catalyst
produced the greatest amount of
catalyst with the lowest concentration of
impurity
•The acid catalyst produced fuel that
was more pure, however there was
slightly less fuel produced
•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
Picture 8: Purity of the biodiesel was
measured via titration
Conclusion
•The enzyme catalyst produced the
most biodiesel that had the smallest
amount of impurity
•Despite the initial cost of the enzyme
it is can be reused hundreds of times
before efficiency is lost (Royon, 2007)
•The study is similar to results of other
researchers, acid and enzyme
catalysts were both more efficient than
the base
Picture 9: Algae being grown in the laboratory setup
at room temp. and regular fluorescent lights
Future Studies
•Running the trial using other types of acid or enzyme
catalysts
•Using different alcohols
•Using different types of algae
•Assess cost efficiency
•Using Le Chatlier’s principles to favor the forward
reaction to biodiesel more
