ResumoA new method of analysing temperature-programmed desorption (TPD) profiles is suggested. Taking into account desorption curves of different heating rates it is shown that the desorption energy distribution function can be calculated by using an extended integral equation without any limiting assumptions about the distribution function and the preexponential factor. The method is demonstrated with simulated data and tested for TPD of different molecules on zeolites.
