| Summary: | Depletion of fossil fuels leads to a research to find an alternative source to replace it.
Esterification and transesterification are the most widely used upgrading method to produce
biofuels with similar properties as petroleum fuels. This study attempted to improve the bio-oil
properties produced from microwave pyrolysis by using heterogeneous transesterification
reaction with calcium oxide (CaO) as catalyst. The objectives of this study are to improve the
pyrolytic bio-oils properties and to determine the ideal weight ratio of methanol/bio-oil for
transesterification reaction. Dried sample of wood waste is subjected to microwave pyrolysis to
produce pyrolytic bio-oil. The bio-oil is then upgraded using transesterification reaction with
the aid of CaO and carried out in two different weight ratio of methanol/bio-oil.
Characterization of the bio-oil before and after transesterification reaction shows that the
properties of bio-oil are successfully improved. Gross calorific values of upgraded bio-oil are
32.949 and 34. 483 MJ/kg. Based on the experimentations, ideal weight ratio of methanol/biooil
is 2:1 which greatly improved certain bio-oil properties. In conclusion, although this weight
ratio improves certain properties of bio-oil the most important properties of bio-oil which is
calorific value are reduced significantly. |
