Abstract
This work aimed to find active and stable solid base catalysts for clean biodiesel production using heterogeneous reaction systems. Three types of catalysts were synthesized and evaluated in the transesterification of triacetin: CaO, γ-Al2O3 modified with Na and K, and MgO modified with Na, Li, Rb and Cs. The influence of the textural proprieties, the type and amount of alkali metal impregnated and the activation with N2 on the basicity and the catalytic behavior were analyzed. Stability of catalysts was analyzed using atomic absorption measurements and reuse reactions. Results showed that metal impregnation does not lead to the formation of stable solids, because they present lixiviation in the reaction system. The CaO maintained a high catalytic activity during five reaction cycles showing its high potential of its use in an industrial process.
