摘要：
The carbonaceous material formed on Al2O3 in the course of the oxydehydrogenation reaction of ethylbenzene to styrene has been considered as the true catalytically active substance. The results of the various analyses made (burn-off experiments; temperature-programmed oxidation, ammonia desorption, ESCA, EPR and SIMS Studies) indicate that the groups containing oxygen in the active coke are quinone/hydroquinone and aroxyl/phenol. © 1990, American Chemical Society.
