Abstract
A model is presented that predicts the transient changes in both the temperature and the conversion of a single coked catalyst pellet during its burning regeneration. The following assumptions are made in developing the model. The coke, consisting of carbon and hydrogen, is dispersed in fine particle form within the catalyst pellet. The hydrogen is first oxidized at a sharp interface in the coke particle and then the carbon remaining outside the interface is gradually oxidized to yield simultaneously CO and CO 2. The temperature in the pellet is uniform and the pellet is in a pseudo steady state. In addition the intrapellet diffusion effect is taken into account. Transient profiles of both the temperature and the conversion in the catalyst pellet were measured during the burning regeneration of coked silica—alumina catalysts. The experimental results were in good agreement with the results predicted by the model.
