Acesso em: 10 jun. 2021.1369-9261http://www.repositorio.ufop.br/jspui/handle/123456789/14219A bimetallic vanadium and niobium oxide catalyst using alumina as support was developed for the conversion of crude glycerol from biodiesel production into formic acid. The high dispersion of the active oxide phase combined with the presence of acid and redox active centers resulted in a high glycerol conversion (490% for 25 h) with a good selectivity for formic acid (B55%). This process is the first example of a heterogeneous liquid-phase process for the conversion of crude glycerol to formic acid, which is an important chemical intermediate currently derived from petroleum feedstock.en-USrestritoArtigo publicado em periodicohttps://pubs.rsc.org/en/content/articlelanding/2020/nj/d0nj00384khttps://doi.org/10.1039/D0NJ00384K
