Paper Abstract

The present work aims the characterization of cumaru and cooking oil waste ethyl biodiesel and evaluates the efficiency during storage of the blends between mineral diesel, ethyl biodiesel of waste cooking oil (BEF) and cumaru (BEC) and in the best of our efforts in research it is published for the first time. The biodiesel were obtained through homogeneous basic catalysis transesterification with conversion of 82.2 ± 1.3% to BEF and 77.2 ± 0.9 % to BEC. The obtaining of BEF and BEC were confirmed by infrared and nuclear magnetic resonance of hydrogen and carbon spectra. Induction times were determined through RANCIMAT method and the value observed to BEC was significantly higher than observed to BEF. The oxidative behavior was corroborated by the thermogravimetric analyzes. In this case, the increase of the heating rate did not affect the behavior of the thermogravimetric curves. The behavior of the blends in presence of mineral diesel was evaluated during storage through the determination of the acid number and the samples that contains mineral diesel showed acid number virtually constant. The samples that contain BEC had also virtually constant acid number while the BEF suffered high increase of the acid number. This study showed an application for the problematic of the disposal of the waste cooking oil beyond the application of cumaru biodiesel as additive to improve others types of biodiesel that are not stable as it.
