Abstract

Tubular and platelet graphite nanofibers were used as catalysts for the oxidative dehydrogenation of ethylbenzene to produce styrene at temperatures between 350 and 577 °C in packed bed tubular quartz flow reactors. The performances of GNF catalysts were evaluated in terms of conversion, selectivity and styrene yield. Tubular GNF showed higher activity than platelet GNF, but the latter showed higher selectivity than the former material. Both types of GNF exhibited significantly better performance than a commercial catalyst when operated under the same conditions.
