NON-ISOTHERMAL BEHAVIOR OF GAS-SOLID REACTIONS BASED ON THE VOLUME REACTION MODEL

[摘要] References(22)Cited-By(3)The effect of heat of reaction in gas-solid reactions is analyzed on the basis of the volume reaction model with a second-order rate equation. The variation of the effectiveness factor in the progress of reaction is graphically represented. For highly exothermic reactions, multiple solutions and the transition of the rate-controlling regime are shown to occur in connection with the magnitude of the Thiele-type modulus. On comparison with the experimental data readily obtainable in the literature, the model is found to satisfactorily describe the data for non-isothermal reaction systems.
