C4 olefin is widely applied as a basic chemical raw stock in the petrochemical and polymer industries for the synthesis of special fuels,rubber,plastics,etc. Conversion of low-carbon alkanes to C4 olefins not only effectively alleviates the shortage of low-carbon olefins in China,but also greatly increases the added value of low-carbon alkanes. This paper reviews the current status and research progress on butane catalytic dehydrogenation technology both domestically and internationally in recent years. The mechanism of n-butane dehydrogenation reaction,the effects of catalyst active components,supports,and additives on catalytic dehydrogenation performance and the reasons for deactivation of dehydrogenation catalysts are summarized. The research prospects of butane dehydrogenation process and catalysts are prospected.
