Abstract

Un proceso de tratamiento del material lignocelulosico incluye un paso de preextraccion en el que la hemicelulosa se extrae del material ligniceculosico. En una forma de realizacion, el paso de preextraccion incluye poner en contacto el material lignoceculosico con una solucion acuosa en condiciones para liberar material ácido del material lignocelulosico en una solucion acuosa, y la solucion acuosa incluye un material básico que por lo menos neutraliza parcialmente el material ácido de modo que la solucion acuosa en el fin del paso de preextraccion tiene un pH dentro de un rango de 4,5 a 11. El proceso también incluye un paso de elaboracion de pulpa, después del paso de preextraccion, en el que el material lignocelulosico se separa en pulpa. El proceso además incluye un paso de adsorcion, después del paso de elaboracion de pulpa, en el que la hemicelulosa se absorbe en la pulpa.
