英文摘要: In addition to the key role played by CO2 as a soft oxidant in the dehydrogenation of ethylbenzene, N2 role as a co-soft oxidant is also significant particularly when Co-Mo based nitrides are used as catalysts. CO2 co-feeding along with a mild oxidant, N2 enhances the activity due to the reverse water gas shift reaction (due to CO2 participation), ammonia synthesis (due to N2 participation) and neutralization of surface acidic sites by ammonia generated during the reaction. The greater activity exhibited during dehydrogenation of ethylbenzene by Co-Mo nitride supported on γ-alumina when compared to the corresponding oxide catalyst is because of the removal of H2 through ammonia synthesis and neutralization of strong acidic sites by this ammonia, in addition to reverse water gas shift reaction. The catalysts are characterized by XRD, surface area and TPR. © 2014 Elsevier Ltd. Citation statistics:
