- Abstract
The prepared Mn-Ce/CNTs catalyst was tested with Temperature-Programmed Desorption (TPD) in this experiment. The adsorption – desorption of NO, NH
3 , O2 on the surface of catalyst were studied and the mechanism of SCR was analyzed. The conclusions were as follows: NH3 was easily absorbed on the surface of Mn-Ce/CNTs catalyst for its significant competitive advantage; it can restrain the absorption of NO. The adsorption performance of NH3 on catalyst surface was far greater than NO. When NO, O2 adsorbed on the catalyst at the same time, the desorption amount of NO from catalyst significantly was less than the NO absorbed only. This shows that the O2 can promote the adsorption of NO on the catalyst in SCR system.- Published
