Experimental Research on the Adsorption Behavior of NH₃ at the Surface of CaO

Abstract:

Temperature programed desorption experiments were carried out for analyzing the TPD spectra of NH₃ desorbed by CaO at different temperature ramp, pressure, and different ratio of CaO to CaSO₄. Moreover, factors affecting on the adsorption process were analyzed. Based on the activation energy of He, NH₃ desorbed at the CaO surface was estimated by experimental spectra and the TPD model.
