Abstract

Procesos para producir alcoholes tales como etanol y propanol en un proceso integrado a partir de una materia prima que consiste en una mezcla de ácidos. En una forma de realización, el proceso comprende el paso de carbonilar metanol en presencia de un catalizador de carbonilación para formar una materia prima que consiste en una mezcla de ácidos que comprende ácido acético y uno o más ácidos superiores, que preferiblemente comprende ácido propiónico. La alimentación de la mezcla de ácidos se hidrogena en presencia de un catalizador de hidrogenación para formar un producto de alcohol crudo que comprende etanol y uno o más alcoholes superiores, que preferiblemente incluyen propanol.Reivindicación 2: El proceso de la reivindicación 1, caracterizado porque en la carbonilación se forma un producto crudo con ácido acético, donde el proceso además comprende los pasos de: separar el producto crudo con ácido acético en una unidad de evaporación parcial por reducción de la presión para formar una corriente sometida a evaporación parcial y una corriente de reciclaje del catalizador; y separar, en no más de una columna de separación, la corriente sometida a evaporación parcial para dar un destilado que comprende un halogenuro de alquilo y un acetato de alquilo, y un residuo que comprende la alimentación de una mezcla de ácidos.Processes to produce alcohols such as ethanol and propanol in an integrated process from a raw material consisting of a mixture of acids. In one embodiment, the process comprises the step of carbonylating methanol in the presence of a carbonylation catalyst to form a raw material consisting of a mixture of acids comprising acetic acid and one or more higher acids, which preferably comprises propionic acid. The acid mixture feed is hydrogenated in the presence of a hydrogenation catalyst to form a crude alcohol product comprising ethanol and one or more higher alcohols, which preferably include propanol. Claim 2: The process of claim 1, characterized in that In carbonylation, a crude product is formed with acetic acid, where the process also includes the steps of: separating the raw product with acetic acid in a partial evaporation unit by reducing the pressure to form a current subject to partial evaporation and a current catalyst recycling; and separating, in no more than one separation column, the current subjected to partial evaporation to give a distillate comprising an alkyl halide and an alkyl acetate, and a residue comprising the feed of a mixture of acids.
