Background of the Study
We all know that carbon dioxide is rapidly increasing, so we the researchers
have thought for another source of fuel that is environment friendly, affordable and
most especially available in our community. The fermented chayote produces ethanol
that is one of the component in making gasoline. It produces less carbon dioxide than
the commercial one
Significance of the Study
Since air pollution is a major problem that is caused by rapidly increasing
carbon dioxide produced by factories, vehicles and etc. This study helps to minimize
the emission of carbon dioxide from vehicles, this also provides potential economic,
environmental and health benefits.
Scope and Limitations
This study focused only on determining if chayote extract is a good source of
bio fuel. This was conducted at the science laboratory of Caraga Regional Science
High School, from the month of July 2011 to February 2012.
Statement of the Problem
This study aims to determine if chayote extract with yeast that undergone
fermentation and distillation can be a source of bio fuel.
Moreover, this study seeks answer to the following:
1. Is there a presence of ethanol from the fermented chayote?
2. How long will it take to distill a fermented chayote?
3. During the fermentation, what are the changes that chayote extract
undergo?
4. Will the finished product can cause corrosiveness to the motorcycle
tank?
Materials and Procedures:
Fermentation:
Materials
250 grams of chayote
Grater
Knife
Since we only have
experimental group, we will
be using the Single Group
Design.
Drainer
Plastic Container
Yeast
Procedure
1. The 250 grams of chayote will be peeled.
2. The product will be grated using a grater.
3. After that it will be drained using a drainer.
4. Then the yeast will be added.
5. It will be put in a plastic container that will be sealed properly.
6. The researcher will wait for about 3-4 days for fermentation and distillation
process will follow.
Distillation:
Materials
Bunsen Burner
Thermometer
Retort
Thermometer Adapter
Beaker
Water Inlet
Water Outlet
Water Condenser
Wire Gauze
Tripod
Procedure
1. A small Bunsen burner will be used as the heat source. Distillation apparatus
will be thoroughly clean.
2. A 300 ml Fermented chayote will be added to the retort.
3. Materials for distillation will be prepared or set up.
4. Bunsen Burner will be turned on.
5. The distillation process will start and the temperature will be monitored by
their boiling point which is 78.3OC for Ethanol and 100OC for water.
6. Final Testing: An empty motorcycle tank will be used, then the finished
product will be poured in it. Then the researchers will wait for about 11 days
to see the effect of the finished product on the motorcycle tank.
