摘要
本文报道了利用程序升温脱附技术考察酸改性的高岭土的比表面与表面酸性的变化。结果表明在600℃煅烧的高岭土经过20wt%的硫酸在90℃处理4h之后具有最大的比表面与表面酸性。
It was reported that calcined Kaolin treated with sulfuric acid was characterized using temperature - programmed desorption （TPD） technique in this paper. The results showed that the high specific area and strong surface acidity can be achieved by treating kaolin using 20 wt% sulfuric acid at 90℃ for 4h,
