CORDEIRO, Claudiney Soares; SILVA, Fabiano Rosa da; WYPYCH, Fernando  e  RAMOS, Luiz Pereira. Heterogeneous catalysts for biodiesel production. Quím. Nova [online]. 2011, vol.34, n.3, pp.477-486. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422011000300021.

The recent increase in the world biodiesel demand, along with the need to reduce costs while improving the environmental sustainability of the entire biodiesel production chain, have led to the search for heterogeneous catalysts that would be efficient and highly amenable to recycling. Many classes of materials have been tested for these purposes. Among these are zeolites, ion-exchange resins, inorganic oxides, guanidines, metal complexes, layered compounds and ionic liquids. This review article describes the structure, properties, synthesis and performance of compounds that are catalytic active in both esterification and transesterification reactions.

Palavras-chave : heterogeneous catalysts; alcoholysis; esterification.
