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.
