Effect of chemical reaction on particle to gas heat transfer

Particle to gas heat transfer studies were carried out by employing the endothermic cyclohexane dehydrogenation reaction. The calculated heat transfer coefficients were on the lower side of those previously reported in the literature for unreactive systems. Previous studies of other investigators with reactive systems suggest that particle to gas heat transfer coefficients may increase with exothermic reaction due to the product molecules leaving the catalyst surface with excess vibrational energy. For an endothermic reaction this effect would result in the calculation of a lower heat transfer coefficient.
