| Abstract: | The loss mechanism by sublimation of active species on subliming catalyst is devided into four categories, parralled, series, side by side and independent sublimation. The desorption isotherm and general kinetics equation of loss by sublimation of active species are recommended. It is proved that Levenspiel's deactivation kinetics equation can be applied to the study of deac- tivation of subliming catalyst. |
