The article discusses the significant shift in propylene production methods caused by the shale gas revolution, pivoting from traditional naphtha cracking to propane dehydrogenation (PDH). This method, while effective, poses challenges due to its endothermic nature and high temperature requirements which increase risks of catalyst sintering and coking. The research highlights recent advancements in zeolite-supported Pt-Sn catalysts and introduces findings on optimizing the length of silicalite-1 (S-1) crystals' b-axis to improve catalyst stability by facilitating the controlled migration of Pt-Sn clusters.
The shale gas revolution necessitated a shift in propylene production technologies, emphasizing on-purpose methods like propane dehydrogenation (PDH) that require robust catalysts.
New findings reveal that the stability and performance of zeolite-supported Pt-Sn catalysts can be significantly enhanced by controlling the length of S-1 crystals' b-axis.
