Abstract

The conversion and selectivity to styrene in the oxidative dehydrogenation of EtPh at 800 K has been foudn to depend on the x=[Sb]/[Sb]+[Fe] ratio in the catalyst, being the highest at x≅0.8. The observed increase in specific catalytic activity is probably caused by the formation of a solid solution of FeSb2O6 in the catalyst.

Abstract

При окислительном дегидрировании этилбензола при 800°К, конверси и селективность к стиролу зависят от отношения x≅[Sb]/[Sb]+[Fe] в катализаторе. Самые высокие значения наблюдаются при x=0,8. Увеличение удельной каталитической активности вероятно вызвано образованием твердого раствора или FeSb2O6 в катализаторе.
