Description:
The utilization of significant reserves of natural and shale gas to meet the ever-increasing demand for olefins has emerged as sustainable alternative to oil cracking processes. A promising way to convert the relatively inert light alkanes into corresponding olefins is their oxidative dehydrogenation. Recently, high activity and selectivity of dispersed forms of boron oxide (BOx) formed on the oxidized surface of the hexagonal boron nitride catalyst was reported. The main goal of this project is to deepen understanding of the structure of the active centers of supported BOx catalysts and activity, selectivity and stability of the individual types of dispersed boron oxide species on various inorganic supports in oxidative dehydrogenation of light alkanes including ethane, propane, n- and iso-butane. This will allow an improved design of selective catalysts for conversion of light alkanes into corresponding olefins.
