Abstract
The present work addresses modeling of the dynamics of heat and mass transfer in the regeneration of adsorptive particle beds focusing on the drying and cooling phase where hot air is first admitted for moisture removal and cold air is introduced to bring about the required bed cooling. Three schemes are studied for the air temperature policy adopted in this drying-cooling phase. The first part of the work presents the development of a lumped parameter dynamic model to describe the evolution of temperature and moisture content within fluidized beds. This is followed by mimicking the behavior of a fixed bed by partitioning the bed into small lumped parameter increments to model its distributed parameter behavior. The third part addresses the effect of intra-particle mass diffusion resistance. The results cover models for constant rate drying and their comparison with the falling rate behavior when the intra-particle mass transfer resistance is considered
