ially procured rubber seed oil (RSO)
were studied to evaluate its potential as viable
feedstock for biodiesel production. The procured
rubber seed oil were characterized for acid value,
saponification value, free fatty acid, flash point,
kinematic viscosity, and refractive indices using
standard methods. Results indicate that the
procured rubber seed oil is a potential biodiesel
feed stocks and it is possible to convert this to
biodiesel with a single stage process. The transesterification
reactions were carried out in the
presence of a solid metal oxide catalyst, calcium
oxide (CaO) and the yield estimated was around
98%.The quality of the biodiesel produced was
comparable with that of the petro diesel which
indicates that this can be blended with the
commercial petro diesel. The calorific value and
cetane number of this biodiesel was higher than
that of the petro diesel which indicates that the
blending may increase the fuel efficiency as well.
