    Abstract: The invention refers to a process and catalyst for obtaining fatty acid methyl esters, by the chemical processing of fats with content of free fatty acids, in order to be used as diesel biofuel, also referred to as biodiesel, intermediates for synthetic biofuels for aviation, or environmental-friendly solvents. The process according to the invention consists of treating the fats with methanol and with super-acid solid catalyst S0427Ti02-La203j at temperatures of 68±2°C, the water resulting din esterification reaction of the fatty acids is separated from methanol in a rectification column and is removed, and methanol is recirculated, until the acidity index of the reaction mass drops under 2 mg KOH/g, the super-acid solid catalyst is removed by filtration, and the filtrate is treated in the next step with a heterogeneous alkaline catalyst, at temperatures of 67±2°C, for 60-90 minute, the catalyst is removed by filtration or centrifugation, glycerine is separated from the methyl esters of fatty acids by decantation or centrifugation, and is then treated with the heterogeneous alkaline catalyst separated before, at temperatures of 67±2°C, for 60-90 minute, the catalyst is removed by filtration or centrifugation, and excess methanol is removed by distillation, first at atmospheric pressure and then under vacuum, glycerine is separated from the methyl esters of fatty acids by decantation or centrifugation, which is finally filtered through an inorganic filtering layer. The heterogeneous alkaline catalyst according to the invention has the molecular formula: CH2,464- 2.5350o,428-o,528No.o3i-o.o43Clo.o3 i-o.o43Cao. io5-o.i29Sio.o64-o.o73, and the process for obtaining it consists of treating the calcium oxide with methanol with a molar ratio of 1 :4, at a temperature of 65°C for 60 minutes, treating the mixture with glycerine with a molar ratio of 1 : 1 to the calcium oxide, at temperatures of 65-70°C for 60 minutes, methanol is removed by distillation from the reaction mass, which is treated with a solvent, with triethanolamine with a molar ratio of 1 :2 to the calcium oxide, and with trialkylchlorosilane with a molar ratio of 1 :2 to the calcium oxide, at ambient temperature, for 60-120 minutes, the resulting suspension is filtered, and the solvent is removed by drying.

    Abstract: The present invention relates to a method for producing biodiesel comprising a step of generating fatty acid alkyl ester and glycerol by a transesterification of animal and vegetable oils and fats and fatty acid alcohols in the presence of porous materials. The method is characterized by a high response speed and high FAME conversion, and can be performed in a consecutive process. Further, according to the method, a high-purity fatty acid alkyl ester and glycol can be produced irrespective of the content of free fatty acids (FFAs). Further, since the method does not use a catalyst, the total processing time and cost can be reduced, and the method is environmentally friendly.
