The review analyzes the data concerning various manifestations of the exothermicity of catalytic reactions. The articles, related to various oxidation and hydrogenation reactions are considered. The diversity of experimental conditions in which exothermic heterogeneous catalysis reactions take place leads to a variety of observed phenomena. Depending on the features of the dynamics of the heat balance of the catalytic reaction, phenomena like the ignition and extinction action, activity oscillations, the appearance of hot zones in the reactor can be observed. In a state of high activity, the mass transfer limitation (MTL) regime is realized. In a flow-through reactor with a catalyst, the polytropic behavior of the reactor with a hot zone at the inlet can be observed. When temperature or reactant concentration is varied, a hysteresis of activity is possible. The influence of strong adsorption of the reagent, catalyst deactivation, and the simultaneous occurrence of an endothermic reaction is considered. The technique of measuring the surface temperature of the catalyst is important, which requires an analysis of the corresponding experimental procedure.

该综述分析了有关催化反应放热的各种表现形式的数据。考虑了与各种氧化和氢化反应相关的文章。发生放热多相催化反应的实验条件的多样性导致了各种观察到的现象。根据催化反应热平衡动力学的特点，可以观察到点火和熄灭作用、活性振荡等现象，可以观察到反应器中热区的出现。在高活性状态下，实现了传质限制​​ (MTL) 机制。在带有催化剂的流通式反应器中，可以观察到在入口处具有热区的反应器的多方行为。当温度或反应物浓度变化时，活动滞后是可能的。考虑了试剂的强吸附、催化剂失活和同时发生吸热反应的影响。测量催化剂表面温度的技术很重要，这需要对相应的实验程序进行分析。
