Abstract
The present invention relates to an improved process for producing dissolving pulp from a hydrolysis-kraft cooking process, and wherein production increases may result in less viscosity reduction and thus not meeting the target viscosities in the dissolving pulp produced. In order to compensate for losses in viscosity reduction in the cook at production increases is the oxygen delignification stage boosted with modest charges of peroxide that introduce an additional viscosity reduction.
