Abstract: Phase composition, reducibilities and catalytic activities of unsupported and γ-alumina-supported NiO-V2O5-based catalysts for ethylbenzene dehydrogenation to styrene have been studied. It has been established that dehydrogenation activities of these samples were due to the presence of mostly vanadium ions and directly depended on their reduction degrees. The maximal level of dehydrogenation activity was attained at the catalyst reduction degree of ~ 30-40% (~ 0.2-0.3 mmol O2 removed) for both unsupported and γ-alumina-supported NiO-V2O5-based samples.

Key words: reduction degree vanadia-containing catalysts catalytic activity ethylbenzene dehydrogenation
