Abstract

The activation-energies of desorption and population of Broensted sites for ammonia adsorbed on H-mordenite have been measured by an advanced IR-TPD technique. There are three different Broensted sites corresponding to three different activation-energies of desorption, 63.6, 49.8, 35.4 kJ/mol and three different population, 0.35, 0.19, 0.10.
