The chlorination of cylindrical lime pellets was studied using thermogravimetric analysis by varying the chlorine concentration, pellet size and temperature. It was determined that the reaction is first order with respect to Cl2. The intrinsic activation energy, E1, is estimated to be 8.09 kcal/gmol in the temperature range of 333°C to 472°C. A two-dimensional expanding grain model that accounts for bulk flow was developed and successfully applied to the lime chlorination system. The effect of varying the chlorine concentration, pellet size, and temperature can be explained in terms of the model. In addition, the modeling results seem to imply that even for a system with solid product expansion, the surface porosity remains finite after the maximum conversion is obtained. |
