Abstract

Mejora del indice de drenaje de la pulpa de papel. Procedimiento para aumentar el índice de drenaje global de la pulpa utilizada en una máquina para la fabricación del papel, o para mantener el índice de drenaje de la pulpa deseado a la vez que se reduce la cantidad de enzima requerida para alcanzar el índice de drenaje deseado, que incluye las etapas de: añadir a la pulpa desde aproximadamente 0,11 hasta aproximadamente 5,51 kg/t de una enzima celulolítica; y añadir a la pulpa desde aproximadamente 1 hasta aproximadamente 1000 ppm de un surfactante seleccionado entre el grupo que consiste en surfactantes no-iónicos y catiónicos; cualquiera puede ser añadido en primer lugar, o ambos juntos.
