摘要: A process for the production of lignin in which is precipitated from aqueous solution by acidification and agitation separated accompanying liquid lignin-containing acid are introduced simultaneous cocurrent flow into an agitated mixing region, not more than 60 minutes after precipitation subsequently washed. The can form a step general treatment lignocellulosic materials to produce one or products including lignin. enables ash content be reduced.
