摘要： 在不同的程序升温速率下,用差热分析获得一组由HZSM-5分子筛的氨脱附曲线。通过数学处理,求得HZSM-5对氨吸附的两类活性点。它们的能量分布分别为:FI(θI)=[53.0+39.7(1-θI)]千焦·摩尔-1,和EⅡ(θⅡ)=(128+8.0(1-θⅡ)]千焦·摩尔-1。
Abstract: Agroup of ammonia desorption curves from the HZSM-5 zeolite have been obtained by thermal analysis at different temperature-programmed rates. Through mathematical treatment, it has been found that there are two kinds of active sites for ammonia adsorption,whose energy distributions are Er(θⅠ) = [53.0 + 39.7 (I-θⅠ)]KJ.mol-1, and EⅡ(θⅡ) = [128+ 8.0(1 -θⅡ)]KJ.mol-1 respectively.
