Abstract
Método para la producción de etanol a partir de fibras de maíz. La presente se refiere a un proceso para la preparación de etanol a partir de una materia prima que contiene fibra de maíz mediante el uso de una serie de pasos de proceso específicamente identificados para el tratamiento de dicha materia prima. Se refiere particularmente al uso de un paso de remojo seguido de un tratamiento de mezcla de ácidos y enzimas que libera azúcares fermentables C₅ y C₆ de dicha materia prima. Se refiere además al uso de una levadura recombinante para convertir azúcares C₅ y C₆ en etanol. Reivindicación 1: Un método para la producción de etanol a partir de un medio de mezcla de azúcares caracterizado porque comprende: a) realizar una fermentación de levadura en una preparación de maíz formando una corriente fermentada; b) destilar etanol de dicha corriente fermentada para producir un residuo entero; c) someter dicha corriente inferior a una separación líquido-sólido formando una torta húmeda de fibra de maíz y una corriente líquida; d) preparar una suspensión de dicha torta húmeda y remojarla en ácido sulfúrico durante una temperatura y tiempo deseados formando una suspensión ácida; e) precalentar dicha suspensión ácida a la temperatura deseada y agregar una mezcla de ácido sulfúrico y ácido fosfórico durante un período de tiempo deseado formando una segunda suspensión ácida; f) cocinar dicha segunda suspensión ácida en una cocina por inyección a una temperatura y un período de tiempo deseados formando una corriente pretratada; g) someter a flashing dicha corriente pretratada en un reactor para reducir su temperatura formando una corriente concentrada; h) neutralizar dicha corriente concentrada con hidróxido de sodio y tratarla con una mezcla de enzimas que liberan azúcares fermentables a una temperatura y período de tiempo deseados formando una corriente tratada con enzimas; i) realizar una segunda fermentación de levadura en dicha corriente tratada con enzimas formando una segunda corriente fermentada; y j) destilar etanol de dicha segunda corriente fermentada.
