Several factors can lead to non-uniform temperature distributions, including:
Heat Transfer Limitations: Inefficient heat transfer between the catalyst and the reactants can result in temperature gradients. Exothermic and Endothermic Reactions: Exothermic reactions release heat, potentially causing local temperature spikes, whereas endothermic reactions absorb heat, leading to cooler zones. Reactor Design: The geometry and scale of the reactor can significantly impact temperature distribution.
