A study on reed pulping with glycol

LI Wan-li, LI Na, LUO Xue-guang (Southwest University of Science and Technology,Mianyang 621002)  
Read wascooked by low concentration glycol at ordinarypressure. Experimentswere carried out on the influence of acid concentration, liquid-to-solid ratio and glycol concentration respectively. The resultsshow that: under ordinary pressure, glycol has favorable cellulose-lignin separate trend and under the conditions of 40% glycol, 10% catalyzer, 50% water, 3% acid and liquid-to-solid ratio of 20:1,the optimal effect of cellulose-lignin separation can beachieved and the quality of pulp is favorable. Glycol can beutilized repeatedly though distillation reclaim and lignin with high purity can be obtained.
