摘要:
分别采用BET法、BJH法和HK法测定了石煤原矿、石煤750 ℃焙烧渣、1 050 ℃焙烧渣3种样品的比表面积、中孔和微孔分布.结果表明，石煤原矿中主要以中孔为主，最可几孔径为4 nm，主要为墨水瓶状孔；750 ℃焙烧3 h，由于有机质氧化，原矿中微孔减少，中孔增加；1 050 ℃焙烧3 h，孔数量急剧减少，大量中孔和微孔消失，只有少量大孔，比表面积显著减小.
Abstract:
Specific surface area, mesopore size distribution and micropore size distribution of stone coal, calcinate of stone coal at 750 ℃ and calcinate of stone coal at 1 050 ℃ were investigated by BET method, BJH method and HK method respectively. It indicated that the pore of stone coal ore is structured mainly by inkbottlelike mesopore, and the most probable pore size is 4 nm. After roasted at 750 ℃ for 3 h, the organic matters in stone coal were oxidated, resulting in remarkable drop in the number of micropore and an increase in the numbers of mesopore. After roasted at 1 050 ℃ for 3 h, most of mesopore and micropore disappeared, only very little megalospore remained, and the specific surface area sharply reduced.
