摘要： The invention concerns a method for producing fatty acid alkyl esters and glycerol by implementing a set of transesterification reactions between at least one plant or animal oil and at least one aliphatic monoalcohol comprising the following steps: (A) introducing, into a three-dimensional ball mill, separately or in a mixture, at least one plant and/or animal oil, at least one aliphatic monoalcohol and at least one heterogeneous and/or homogeneous catalyst in order to form an initial mixture; (B) milling said initial mixture at a temperature of less than or equal to 50°C, and preferably of less than or equal to 25°C, in a three-dimensional ball mill, for a holding time of less than or equal to 5 minutes, and preferably of between 5 and 30 seconds and typically of between 5 and 15 seconds; (C) recovering, at the outlet of the three-dimensional mill, a final mixture comprising at least fatty acid alkyl esters, glycerol, the catalyst and the unreacted aliphatic monoalcohol; and (D) separating, from this final mixture, a first phase comprising the fatty acid alkyl esters and a second phase comprising the glycerol, the unreacted aliphatic monoalcohol and the catalyst.
