Abstract

Abstract The uses of kraft lignin (KL), obtained from the black liquor (BL) in the pulping process, allow the production of activated carbon (AC), a product with high added value in the pulp mill. The AC can be used in three different sectors in a cellulose pulp mill: sectorial treatment of the cellulosic pulp bleaching filtrates; wastewater treatment; and in the treatment of water received by the mill. Thus, this article considers the steps in the production of AC, their types, and the advantages and challenges of its use in the kraft cellulose pulp mill as well as in other industries.

纸浆厂使用硫酸盐木质素作为活性炭的可能替代品——综述

摘要从黑液（BL）中获得的硫酸盐木质素（KL）在制浆过程中的用途，允许在纸浆厂生产具有高附加值的活性炭（AC）。AC可用于纤维素纸浆厂的三个不同部门：纤维素纸浆漂白滤液的部门处理；污水处理；以及在由磨机接收的水的处理中。因此，本文考虑了AC的生产步骤、类型，以及在硫酸盐纤维素纸浆厂和其他行业中使用AC的优势和挑战。
