Applicability of protolytic mechanism to steady-state heterogeneous dehydrogenation of ethane revisited

摘要: Abstract This article revisits the applicability of traditional protolytic mechanism in heterogeneous activation ethane on basis new evidences achieved through various molecular sieves, and gives an overview progress catalytic dehydrogenation to ethylene presence or absence oxidant. The results acidic alkali metal ion catalysts have been compared those chromium iron oxides. over sites has explored by preventing interference All played a negative role dehydrogenation. Even oxygen as strong reactive agent could not alter prevailing mechanism. experimental data proved that Bronsted acid–Lewis base is effective this event. A Lewis acid–hydride was alternatively realized favored pathway from ethylene. effect alumina silica framework also dissected.
