The present invention relates to the synthesis and use of a pumice-based catalytic material that can be used as a heterogeneous catalyst for the transesterification reaction and that allows obtaining fatty acid methyl esters, biodiesel, at low temperatures from vegetable oils and used frying oils.
This is an innovative process for obtaining biodiesel from used oils and non-edible oils.
Avoid the main disadvantages of the conventional method of obtaining biodiesel when using this type of raw material.
A more environmentally friendly method than the conventional method, which would allow the production of biodiesel through continuous operation processes.
