Abstract

For the first time the phenomenon of a temperature hysteresis in the exothermic heterogeneous catalytic reactions of CO hydrogenation (methanation) and propene is discussed; the assumption is made, that the reason of hysteresis is the local overheating of the active centers caused by the complicated dissipation of the released energy through the dispersed particles of the catalyst.
