- ... This study aimed to obtain ethyl esters (EEs) from macauba pulp crude oil, using heterogeneous-acid catalyst, varying the temperature of (trans)esterification, ethanol-to-oil molar ratio (MR) and catalyst content. Catalyst Amberlyst 15 characterization showed high concentrations of active sites of 3400 μmol g−1 and a surface area of 31.3 m2 g−1, which associated with the resin macroporous structur ...
