Process for the production of biocombustible or biofuel mixtures suitable for different conditions of use, starting from refined or raw vegetable oils, including those extracted from seaweed, and/or from used food oils and animal fats, each of which is pre-treated with specific treatments in order to yield a dried refined oil. The latter then undergoes transesterification with an excess of lower alcohols or bioalcohols, and a subsequent separation into a raw glycerine-based phase and a phase containing mixtures of fatty acid alkyl esters and the excess alcohols or bioalcohols.;The excess amount of lower alcohols/bioalcohols can be partially or completely recovered from the obtained mixture, or the mixture itself may be integrated with additional quantities of the same or different lower alcohols/bioalcohols, thereby yielding combustible products and ecological fuels suitable for various environmental conditions and for the types of apparatus and engines they must be employed in.;The product can either be used by itself or as the main or secondary ingredient of a mixture with conventional fuel. |
