Özet

The main purpose of this study is the production of valuable chemicals from ethane with a minimum selectivity of 90% and high stability with a catalyst lifetime of minimum of 12 hours. In this regard, Cr and Mo-containing MgO and MgO encapsulated carbon-core mesoporous (MgO-C, core-shell model) catalysts were prepared through a hydrothermal co-precipitation method. The non-oxidative dehydrogenation of ethane was conducted in microwave heated reactor system. Mo-based MgO encapsulated carbon-core catalysts present higher activity and selectivity towards hydrogen and ethylene production compared to Cr-based MgO-C supported catalysts. Core-shell model catalyst showed the high surface area and high microwave absorption capability due to the physical properties of mesoporous carbon So, the highest ethane conversion (66%) and the best hydrogen selectivity (%96) were obtained over the mesoporous 5Mo@MgO-C catalyst.
