The catalyst for dehydrogenation of diethylbenzene(DEB) to divinylbenzene(DVB) was studied. Potassium-promoted iron oxide catalyst was mainly used for ethylbenzene dehydrogenation. If potassium alkli or salt was used directly as promoter, it was noted that the loss of potassium component from the surface of the catalysts pellet result in deactivation. When potassium promoter was added as kaliophilite(KAlSiO4). It was shown that the latter way of adding potassium promoter not only keeps the depression of carbonaceous deposits but also controls the loss of potassium component(the value of loss of potassium component has been reduced three times) , thus making the catalyst having a higher dehydrogention activity.
