煤氧化热解过程中H2产生规律的实验研究
The Experimental Study of H2 Producing Law in Coal Oxidation Pyrolysis Process
-
摘要: 通过对长焰煤,肥煤以及无烟煤进行氧化升温实验研究,得出3种煤在氧化热解过程中H2产生规律。结果表明:这3种煤H2生成趋势基本相同;煤变质程度越高,H2开始析出时温度就越低;煤自燃倾向性等级越高,H2开始析出时温度越低。Abstract: Through studying on the oxidation temperature increasing experimental of long flame coal,fat coal and anthracite coal,the H2 produced laws of three coals are obtained during oxidation thermal decomposition.The result shows that the H2 production trends of three coals are basically same.The higher the coal metamorphic grade is,the lower the temperature is when H2 begins to precipitate;the higher the spontaneous combustion tendency is,the lower the temperature is.
