Characterization of Biodiesel Obtained from Vegetable Oil; Conventional and Residual

This work shows the description of biodiesel production, characterization and tests of performance on a diesel engine, using conventional vegetable oil and residual vegetable oil to generate it. The process to obtain the biodiesel by transesterification is described and three characteristics of both types of biodiesel were determined: pH, density, viscosity and electrolytic conductivity. Then, biodiesel is characterized electromechanically, through the performance of the biodiesel in a diesel engine, whose characteristics are acquired from a test bench where its efficiency in power, torque and energy consumption is determined. Finally, the comparison of the two types of biodiesel is made in order to define the biodiesel with the best characteristics.
