Recent progress on the traditional and emerging catalysts for propane dehydrogenation

Propene is an important chemical raw material with continuously growing demand from the propene downstream industry. Compared with the traditional catalytic cracking process and steam cracking of naphtha, the propane dehydrogenation (PDH) process is an attractive alternative to efficiently produce high-purity propene. Presently, the traditional Pt-based and Cr-based catalysts for PDH are mainly used in commercial processes. And the non-noble metal catalysts and carbon catalysts for PDH also receive increasing attention with the development of research both from academia and industry. In this review, the recent progress on the traditional catalysts, the emerging non-noble metal catalysts, and carbon catalysts was summarized, together with the discussion of the key research issues and development direction of these PDH catalysts. This review could provide the theoretical and technical foundation for developing novel high-efficiency PDH catalysts.
