Abstract

Un proceso para purificar etanol usando un reactor de terminación para la eliminación de impurezas, tal como acetato de etilo, acetaldehído, ácido acético y dietil acetal, presentes en el etanol después de la destilación de un producto crudo de un reactor de hidrogenación. El reactor de terminación puede reducir las impurezas en presencia de hidrógeno y un catalizador o puede hidrolizar las impurezas.Reivindicación 1: Un método para purificar un producto de etanol, caracterizado porque comprende: hidrogenar ácido acético en un reactor primario en presencia de un primer catalizador para formar un producto de etanol crudo; separar por lo menos una porción del producto de etanol crudo para dar una corriente intermediaria que comprende etanol y una o más impurezas que se seleccionan entre el grupo que consiste en: acetato de etilo, acetaldehído, ácido acético, y dietil acetal; y poner en contacto a la corriente intermediaria e hidrógeno en un reactor secundario en presencia de un segundo catalizador, en condiciones de selectividad, para hidrogenar dichas una o más impurezas para formar un producto de etanol purificado.A process for purifying ethanol using a termination reactor for the removal of impurities, such as ethyl acetate, acetaldehyde, acetic acid and diethyl acetal, present in ethanol after distillation of a crude product from a hydrogenation reactor. The termination reactor can reduce impurities in the presence of hydrogen and a catalyst or can hydrolyze impurities. Claim 1: A method for purifying an ethanol product, characterized in that it comprises: hydrogenating acetic acid in a primary reactor in the presence of a first catalyst to form a crude ethanol product; separating at least a portion of the crude ethanol product to give an intermediate stream comprising ethanol and one or more impurities that are selected from the group consisting of: ethyl acetate, acetaldehyde, acetic acid, and diethyl acetal; and contacting the intermediate stream and hydrogen in a secondary reactor in the presence of a second catalyst, under selectivity conditions, to hydrogenate said one or more impurities to form a purified ethanol product.
