Реферат:
The foundations of the theoretical concept of nonbranched radical-chain reactions involving heterogeneous catalysts are considered for hydrocarbon pyrolysis. These include the phenomenological model and the concept of the “catalysis sphere.” Surface active sites S participate in chain propagation along with hydrocarbon radicals R· from the gas phase. Surfaces show either inhibiting or neutral action depending on the ES–R bond energy. If the ES–R value is comparable with the energy of the breaking bond in the reacting molecule, the reaction accelerates due to the acceleration of either the heterogeneous or homogeneous component of the overall rate of the process. In the latter case, the catalyst ensures the generation of additional radicals for the gas phase, which result in the formation of a catalysis sphere. The catalysis sphere is defined, the radical distribution in it is presented, and its properties and role in radical-chain processes are discussed.
