Catalyst Development and Design in Propane Dehydrogenation
Light-alkane direct dehydrogenation reaction, which has received wide attention in recent years, is an important industrial technology for the petrochemical fields. There are great progresses and developments on the Pt- and/or non-noble metal-based heterogeneous catalysts for selectively activating the C—H bond with the purpose of high alkene productivity. However, the coke formation and sintering of the metal would cause the catalyst deactivation. Thus, it is still a challenge to achieve catalysts with high catalytic performance and stability. This review describes recent advances in the strategies for promoting the metal dispersion and tuning the metal electron structures: (1) introduction of promoters; (2) synthesizing the highly active single-atom sites; (3) alteration of the support properties and encapsulation of subnanometer-sized clusters into the microporous zeolites. In addition, the elimination of coke on the support can be realized by decreasing the acid sites and co-feeding other gas flows. The alternative catalysts, such as non-noble metals and metal oxides, are also summarized. The active sites, reaction pathways and deactivation mechanism over various catalysts are also discussed, which is expected to help the efficient catalyst design for high selectivity to propene products. The challenges and perspectives of catalysts on light-alkane dehydrogenation are proposed for further development.
