The effect of gas-particle heat and mass transfer on the reaction rate and the catalyst temperature in an adiabatic reactor with strongly endothermic reaction was studied using a mathematical model. It was found that subcooling of the catalyst surface against the reaction mixture is the prevailing phenomenon affecting the effectiveness factor and the longitudinal profile of the reaction rate.
