Heterogeneous nanocatalyst for the production of esters of fatty acids from renewable sources

摘要

Heterogeneous nanocatalyst for the production of esters of fatty acids from renewable sources. The present invention relates to the reaction of transesterification of oils and fats for the production of 5 alkyl esters suitable for use as a substitute of diesel or added to it.In this invention, esters are produced by single step via heterogeneous catalysis, employing new nickel catalysts, [(NiO), and sodium chloride (NaCl), 4] and [(NiO), 1s / sodium chloride (NaCl), 25 Al203] in nano scale in the transesterification at 1 the reaction of 65 u00ba C and quantity The nanocatalyst used 3.0% [(NiO), and sodium chloride (NaCl), and 0.5% [4] (NiO), 1sl (NaCl).25 - Al203] in relation to the mass of the oil used. Very mild reaction conditions when compared with the traditionally reported in the state of the art, and, above all, producing very high levels of esters.
