페로프스카이트형 산화물 촉매상에서 이산화탄소 존재하의 에틸벤젠의 산화적 탈수소

초록

Energy saving of dehydrogenation of ethylbenzene can be realized by using the CO2 as an oxidant due to alleviation of chemical equilibrium. Although this process has the advantage, it gave a stricking drawback of catalyst deactivation during the reaction due to carbon deposition. Perovskite-type oxides are useful for catalysts because of high thermal stability, dispersion of components and redox property. Therefore, in this work, perovskite-type oxides were synthesized by sol-gel method using several components (Ca, Ti, Fe, La, Sr, V) and tested with a fixed bed reactor.
