摘　　要：次氯酸钠水溶液对煤的氧化解聚可以改善煤的透气性,通过测定不同条件下次氯酸钠水溶液对高河煤的相对氧化率来研究次氯酸钠水溶液对高河煤的氧化解聚规律。实验分析发现:氧化率随反应时间的增加而增加;浓度在6%左右时氧化率较高,为适宜的反应浓度;温度在30℃左右时氧化率较高,为适宜的反应温度。The oxidative depolymerization of coal in NaClO aqeous solution was favor of improving the permeability of the coal.The paper studied the oxidative depolymerization rule of Gaohe coal in NaClO aqueous solution,which was according to determining the relative oxidation rate of Gaohe coal in NaClO aqueous solution under different conditions.Experimental analysis found that:with the increased of the reaction time,the oxidation rate appeared increasing;the oxidation rate was higher when the concentration at about 6%,as the reaction concentration appropriate;the oxidation rate was higher when the temperature around 30℃,that was the appropriate reaction temperature.
