✦ Synopsis

Abshct

-A theoretical analysis of an adiabatic non-isothermal single-pellet diffusion reactor shows that nonisothermal effects can alter the value of the centerplane concentration. Deviation from isothermal behavior is significant under exothermic conditions where multiplicity of solutions can lead to reactor instabilities or falsification of reaction parameters. Conversely, it is shown that the internal isothermal model is a good approximation to detect non-isothermal pellet behavior from centerplane concentration measurements. lNTROIKMTTlON The single pellet diffusion reactor (SPDR) has proven to be a useful tool to analyze the interaction of diffusion mass transfer and catalytic activity&31.

The kinetics of adsorption in bidisperse pellets has been largely studied under isothermal condition. But due to large heat of adsorption, the isothermal models may lead to erroneous results. The present paper proposes a non-isothermal bidisperse model, taking into account two scale mass diffusion (
