Abstract

La presente está relacionada con un proceso para preparar una pulpa de alto rendimiento que comprende: a) tratar químicamente un material que contiene lignocelulosa mediante un sistema de oxidacion que comprende por lo menos un oxidante no enzimático sustancialmente libre de ozono y dioxido de cloro y un activador a un pH de aproximadamente 2 y alrededor de 6,5, y b) tratar mecánicamente el material que contiene lignocelulosa por un tiempo suficiente como para producir una pulpa de alto rendimiento, donde el material que contiene lignocelulosa es tratado químicamente antes de y/o durante cualquier etapa de tratamiento mecánico, y donde el material que contiene lignocelulosa no es químicamente tratado a un pH de aproximadamente 11,5 a alrededor de 14 entre las etapas a) y b).This is related to a process for preparing a high-performance pulp comprising: a) chemically treating a material containing lignocellulose by an oxidation system comprising at least one non-enzymatic oxidant substantially free of ozone and chlorine dioxide and a activator at a pH of about 2 and about 6.5, and b) mechanically treating the lignocellulose containing material for a sufficient time to produce a high yield pulp, where the lignocellulose containing material is chemically treated before and / or during any stage of mechanical treatment, and where the lignocellulose containing material is not chemically treated at a pH of about 11.5 to about 14 between steps a) and b).
