Estudo do potencial da celite como material adsorvente de impurezas em biodiesel.

Abstract

The research purpose was the evaluation of the potential of the mineral celite as adsorbent of biodiesel. Therefore, the biodiesel used in this work was synthesized from residual frying oil. After the transesterification process in order to obtain the biodiesel, the fuel was filtered by the adsorbent materials and analyzed by infrared and chromatography. Celite-filtered biodiesel was compared with other adsorbent elements such as active carbon and rice husk lignin. Preliminary results of the analysis of celite filtered biodiesel revealed a sevenfold reduction in the acid value established by the ANP compared to unfiltered biodiesel. In addition, other parameters such as viscosity and metal content, analyzed via X ray diffraction spectroscopy (EDX), revealed celite as a very promising adsorbent material, especially in terms of cost-effectiveness when compared to other materials currently used.
