Abstract
El empleo de la borra de café para obtener biodiesel tiene por objeto el reciclado de este importante residuo y la produccion de un combustible de carácter renovable y de bajo impacto ambiental. Para la obtencion de biodiesel se emplea la transesterificacion in situ, que permite una reduccion de la energía usada en el procedimiento. Los residuos de café se conservan en frío hasta su procesamiento, se secan en estufa a 105sC y se maceran con metanol anhidro en una relacion 1:1 (P/V) durante 24 horas. A la mezcla resultante se le agrega ácido sulfurico concentrado y metanol. El volumen de ácido sulfurico usado corresponde a un 100 % del volumen de aceite presente en la borra del café. El volumen de metanol agregado corresponde a una relacion molar (metanol, triglicéridos) de entre 100:1 y 300:1. Esta mezcla es calentada a reflujo a 60-65sC, bajo agitacion, entre 1-3 horas, pudiendo también emplearse combinaciones de menores temperaturas con tiempos mayores. El producto de la transesterificacion se lava con éter de petroleo, hexano o éter etílico. La fase orgánica se separa y se lava con agua destilada hasta neutralidad. Finalmente, se deshidrata con sulfato de sodio anhidro u otro agente desecante y el disolvente orgánico se evapora a presion reducida.The use of coffee waste to obtain biodiesel is aimed at recycling this important waste and producing a renewable fuel with a low environmental impact. In order to obtain biodiesel, in situ transesterification is used, which allows a reduction of the energy used in the process. The coffee residues are kept cold until processed, dried in an oven at 105sC and macerated with anhydrous methanol in a 1: 1 ratio (P / V) for 24 hours. To the resulting mixture is added concentrated sulfuric acid and methanol. The volume of sulfuric acid used corresponds to 100% of the volume of oil present in the coffee bean. The volume of methanol added corresponds to a molar ratio (methanol, triglycerides) of between 100: 1 and 300: 1. This mixture is heated to reflux at 60-65sC, under stirring, between 1-3 hours, and combinations of lower temperatures with longer times may also be used. The transesterification product is washed with petroleum ether, hexane or ethyl ether. The organic phase is separated and washed with distilled water until neutral. Finally, it is dehydrated with anhydrous sodium sulfate or other drying agent and the organic solvent is evaporated under reduced pressure.
