ABSTRACT Cooking, oxygen delignification, and ECF bleaching characteristics of Scandinavian pine were studied using a recently implemented lab. scale displacement cooking system.  Cooking with white liquor was varied over a wide range in order to produce pulps of varying delignification degrees and yields with const. impregnation and hot black liquor treatment.  The pulps were then oxygen delignified and bleached with a D(EOP)​DD sequence, again varying conditions in order to evaluate delignification and brightness …
