Abstract

Un proceso para la producción selectiva de etanol mediante la reacción de ácido acético en fase de vapor sobre una composición catalizadora hidrogenante para formar etanol. Mediante la reacción del ácido acético e hidrógeno sobre cobalto y paladio apoyados en grafito o sobre cobalto y platino apoyados en sílice, se puede producir selectivamente etanol en una fase de vapor a una temperatura de aproximadamente 250sC. Reivindicación 1: Un proceso para la formación selectiva y directa de etanol a partir de ácido acético, caracterizado porque consiste en: poner en contacto un flujo de alimentación que contenga ácido acético e hidrógeno a una temperatura elevada con un catalizador hidrogenador adecuado que contenga 0,1 por ciento por peso y 20 por ciento por peso de cobalto en un soporte catalizador adecuado y, opcionalmente, un segundo o un tercer metal soportado sobre dicho soporte y en el cual dicho segundo o tercer metal se seleccionan del grupo formado por paladio, platino, rodio, rutenio, renio, iridio, cromo, cobre, estano, molibdeno, tungsteno, vanadio y cinc. Reivindicación 22: Un proceso para la formación selectiva y directa de etanol a partir de ácido acético, caracterizado porque consiste en: poner en contacto un flujo de alimentación que contenga ácido acético e hidrógeno a una temperatura elevada con un catalizador hidrogenador adecuado que contiene 1 por ciento por peso y 15 por ciento por peso de cobalto en un soporte catalizador adecuado y un segundo metal soportado en dicho soporte y en el cual dicho segundo metal se selecciona del grupo formado por paladio, platino, cobre, estano, molibdeno y tungsteno.
