Extended impregnation kraft cooking of softwood : Effects on reject, yield, pulping uniformity, and physical properties

Converting wood into paper is a complex process involving many different stages, one of which is pulping. Pulping involves liberating the wood fibres from each other, which can be done either chemically or mechanically. This thesis focuses on the most common chemical pulping method, the kraft cookin...
