摘要

PROCEDURES AND SYSTEMS FOR BLANKING LIGNOCELLULOSE PULPES AFTER SODA AND ANTHROKINONE COOKING. Process for bleaching pulps following baking of lignocellulose material with soda and anthraquinone. The process can produce a whiteness paired with Kraft pulp bleaching when a similar bleaching sequence is used. In some cases, the bleaching sequence may be O-A-Do-Eop-D, O-A-ZDo-Eop-D, A-Do, or A-ZDo.
