Abstract

La presente invencion se refiere a un método para tratar materias primas lignocelulosicas que contienen pectina en un proceso de pulpado de alto rendimiento que utiliza una o más etapas de tratamiento en condiciones alcalinas. La invencion proporciona un método para controlar la etapa de tratamiento alcalino, en el cual el álcali es aplicado en la etapa de tratamiento a baja temperatura antes de una o más etapas consecutivas de tratamiento a la misma temperatura o a temperatura más elevada. La presente invencion proporciona asimismo pulpa, papel, carton o papel tisu que se obtiene mediante dicho método.
