Evaluation of mixtures of petrodiesel, palm biodiesel and copaiba oleoresin in an electrical plant

Abstract:

The performance of mixtures of petrodiesel, palm biodiesel and refined copaiba oleoresin as fuel in an electric generator is analyzed. Tests were carried out in a power plant provided with a secondary feeding system to monitor the performance of the mixtures and of the reference fuel under full load conditions. Influence of percentage of oleoresin in mixtures on fuel consumption, power delivered and emission of exhaust gases were studied. A decrease of up to 19% was established in power generated by plant with respect to energy supplied by the diesel-operated engine. In relation to gases emission, the addition of refined copaiba oleoresin to fuel, reduces concentration of CO and SO2 in exhaust gases. According to the results, incorporation of copaiba oleoresin to commercial diesel could be an environmentally friendly option. However, increase in viscosity of fuel could limit its use in automotive applications.
