Process for the production of biocombustible or biofuel mixtures suitable for different conditions of use, starting from refined or raw vegetable oil s, including those extracted from seaweed, and/or from used food oils and an imal fats, each of which is pre-treated with specific treatments in order to yield a dried refined oil. The latter then undergoes transesterification wi th an excess of lower alcohols or bioalcohols, and a subsequent separation i nto a raw glycerine-based phase and a phase containing mixtures of fatty aci d 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 q uantities of the same or different lower alcohols/bioalcohols, thereby yield ing combustible products and ecological fuels suitable for various environme ntal conditions and 'for the types of apparatus and engines they must be emp loyed in. The product can either be used by itself or as the main or seconda ry ingredient of a mixture with conventional fuel. |
