Optimization of the biodiesel production from castor oil and influence of the temperature on the rheological behavior of its blends with diesel fuel(Abstract)

摘要

In agreement with the new legislation in energy, Brazil will add 2% (B2) of biofuel in the conventional diesel until 2008. Perhaps this addition can reach 5% (B5). This work consisted of three stages (1) to evaluate the influence of the reaction time, temperature, molar ratio (alcohol/oil) and catalyst concentration in the alkaline methanolysis (NaOH) of the castor oil (biodiesel), identifying the main effects caused by process variables
