摘要
在用多种氧化剂对煤炭脱硫效果进行比较研究的基础上 ,筛选出脱硫效果最好的冰醋酸与过氧化氢混合物氧化剂。采用单因子法考察了氧化剂种类、煤与氧化剂的配比、氧化反应温度、反应时间、煤的粒度、冰醋酸与过氧化氢的配比对脱硫率的影响 ,优选出了冰醋酸与过氧化氢氧化法脱除原煤中有机硫的最佳工艺条件为 :冰醋酸与过氧化氢的体积比为 1∶1,反应温度为 10 4℃ ,反应时间为 1h ,煤与氧化剂的配比为 3g∶5 0mL ,煤的粒度为粒径小等于0 .2 3mm。在最佳条件下 ,原煤脱硫率可达到 6 0 .8%。
Based on the comparison of coal desulfurization effects of several kinds of oxidants,the mixed oxidant of glacial acetic acid and hydrogen peroxide was selected as the best.The effects of the kinds of oxidants,the ratio of coal to oxidant,the oxidation temperature and time,the coal granule size,the ratio of glacial acetic acid to hydrogen peroxide on desulfurization efficiency were studied in single factor method.The optimum operating conditions for coal desulfurization with the mixed oxidant of glacial acetic acid and hydrogen peroxide were determined as follows:volume ratio of glacial acetic acid to hydrogen peroxide=1/1,reaction temperature 104℃,reaction time 1 h,ratio of coal to oxidant=3g∶50mL,coal granule size≤0.23 mm.Under the optimum conditions,the coal defulfurization efficiency can come up to 60.8%.
