Effects of Different Pretreatment Conditions on Chromia Catalyst Performance during Hydrocarbon Dehydrogenation Reaction

Chromia catalysts were synthesized by impregnation method. The performance of the catalyst on hydrocarbon dehydrogenation reaction was investigated under different pretreatment conditions. The activity of the catalyst was improved under water steam pretreatment. The catalyst had no change during water steam pretreatment. The regeneration of the catalyst was better kept.
