Activation energy distribution in temperature-programmed desorption : modeling and application to the soot-oxygen system

摘要: A desorption model has been developed to determine the activation energy distribution of surface oxygen complex in TPD (temperature-programmed desorption). This two major advantages: 1) can be calculated directly from measurable data; 2) is principle capable dealing with any temperature programs experiments. Experimental studies an uncatalyzed soot material three different have carried out and resulted same using present model. The obtained found approximately Gaussian
