- Abstract
Non-oxidative propane dehydrogenation is an endothermic reaction requiring thermally stable and regenerable catalysts to produce propylene. In this work, we investigate bimetallic CoXNi2-XP as an alternative, non-noble metal propane dehydrogenation catalyst. Co1Ni1P displayed higher propylene selectivity than Co2P and higher site-normalized propylene production rates than Ni2P. Different compositions of CoXNi2-XP catalysts were evaluated for propane dehydrogenation with oxidative regeneration in between each cycle. Ni-rich Co0.5Ni1.5P showed increased propylene production upon regeneration due to the formation of the Ni12P5 phase during reaction. In contrast, Co1Ni1P and Co1.25Ni0.75P showed the ability to recover > 50% of the initial activity for at least 3 oxidative regenerations, while maintaining high propylene selectivity without any phase change. This study showcases the enhancement in stability and propane dehydrogenation performance of Ni2P through Co incorporation and Ni:Co ratio control.
