摘要：

A shell progressive kinetic model is used to determine the temperature rise in a spherical pellet for a gas‐solid diffusion controlled reaction. The effects of heat and mass transfer resistances in the gas film as well as inside the pellet are investigated. The predicted temperature rise may be severe enough to cause sintering to catalyst pellets in which reactions such as combustion of coke occur.
