A new method for the pulping of aspen branch wood

摘要

Based on the BECMP production line,this article introduced the main technological process for the production of BECMP pulp using aspen branch wood as the raw material.For better understanding of the new pulping method,Compared with the widely applied production line of P-RC APMP,the relevant pulping performances and operational efficiencies of BECMP were evaluated.The results showed that: using aspen branch wood in BECMP pulping was technically feasible,and it had more benefits as effective use of the lignocellulose raw material,energy saving,and reduction in water consumption.Most notably,the properties of the pulp met the requirements of APMP-based pulp mills,and simultaneously,its tensile strength was better than that of the APMP pulp.
