Abstract: OP-I-17 Механизм неразветвленных радикально-цепных реакций пиролиза углеводородов с участием гетерогенных катализаторов The mechanism of nonbranched radical-chain reactions involving heterogeneous catalysts is considered for hydrocarbon pyrolysis. Surface active sites S participate in chain propagation along with hydrocarbon radicals R from gas phase. 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 catalysis sphere. The catalysis sphere is defined, the radical distribution in it is presented, and its properties are discussed. Секция: Секция I: Reductive-oxidative heterogeneous catalysis
