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.
