Dehydroaromatization Pathway of Propane on PtZn/SiO2 + ZSM-5 Bifunctional Catalyst

Che-Wei Chang et al.

Summary: The Cyclar process, utilizing gallium-loaded ZSM-5 catalysts, has limitations in BTX yield due to light gas formation. This study investigates the relative rates and selectivity for propane conversion on different catalytic components, suggesting that using a PtZn alloy catalyst can minimize light gas production and improve aromatics yield. Additionally, the bifunctional PtZn/SiO2 + H-ZSM-5 catalyst shows higher yields and selectivity for aromatics formation compared to ZSM-5, indicating the potential for optimizing the aromatization process.

Propane dehydrogenation: catalyst development, new chemistry, and emerging technologies

Sai Chen et al.

Summary: The review discusses recent advances in understanding the PDH process, including emerging technologies, catalyst development, and new chemistry for regulating catalyst structures and inhibiting catalyst deactivation. Analysis and discussion on active sites, reaction pathways, and deactivation mechanisms of PDH over metals and metal oxides, as well as their dependent factors, are provided to enable efficient catalyst design for minimizing reaction barriers and controlling selectivity towards propylene. Challenges and perspectives of PDH over heterogeneous catalysts are also proposed for further development.
