Oxidative dehydrogenation of ethylbenzene on vanadium-magnesium oxide catalysts
Summary Oxidative dehydrogenation of ethylbenzene to styrene at 470°–500°C was studied on a vanadium-magnesium oxide catalyst: at an ethylbenzene s.v. of 0·35 to 1·2 hr−1 and ratios of ethylbenzene: oxygen:steam of 1:0·8 to 1·3:7 to 20. Styrene yield reached 74%, with a process selectivity of 90%. The catalyst showed a high operating stability during 5000 hr without regeneration. The following is recommended for simulating an industrial reactor: ethylbenzene : O2:H2O ratio of 1:1:7, C8 s.v. = 0·35 hr−1 at 470°–490°C.
