METHODS OF PROCESSING LIGNOCELLULOSIC PULP WITH CAVITATION

摘要

Methods of treating lignocellulosic pulp with cavitation are disclosed. The methods include delignifying a slurry comprising lignocellulos pulp in the presence of cavitation and bleaching a delignified pulp in the presence of cavitation. Delignification can be done by contacting a lignocellulosic pulp slurry with an oxidizing agent in a cavitation zone. Bleaching can be carried out by contacting a delignified pulp slurry with a bleaching agent in a cavitation zone.
