Abstract

Un método para hidrolizar el material celulósico leñoso que contiene lignina y bolsas de aire comprende el impregnar el material celulósico leñoso con un primer álcali que tiene un pH de a partir el 10 a 14 tal que el primer álcali esté en contacto con la lignina dentro del material celulósico leñoso. Después de esto, el material celulósico leñoso se hace avanzar a través de un recipiente bajo la presión de la gravedad para la conversión de la hidrólisis ácida del material celulósico a los azúcares. De acuerdo con otros métodos, se puede aplicar ultrasonido durante la impregnación o en el recipiente o ambos bajo la presión de la gravedad.
