Abstract利用喷动载流床模拟煤拔头工艺,在550,650,750和850℃热解温度下对大同烟煤进行热解得到拔头半焦.采用氮吸附法对该烟煤及其半焦的孔隙结构进行了研究.结果表明,拔头半焦的孔隙发达度都弱于原煤;由低到高4个热解温度下挥发分析出率(Y)依次为7.89%,21.79%,22.12%,39.33%,中孔尺寸随Y增加而减小,微孔和大孔尺寸及总孔体积和总孔比表面积基本随Y增加而增加;550℃时挥发分的析出对孔隙结构的发展无明显有利影响.从原煤到半焦(热解温度由低到高),样品满足BET吸附等温式的相对压力范围依次为0.101~0.351,0.093~0.201,0.072~0.152,0.032~0.053,0.058~0.108,BET比表面积与NLDFT总孔比表面积变化趋势一致.
