摘要:
Improved methods of oxidative dehydrogenation (ODH) of short chain alkanes or ethylbenzene to the corresponding olefins, and improved methods of oxidative coupling of methane (OCM) to ethylene and/or ethane, are disclosed. The disclosed methods use boron- or nitride-containing catalysts, and result in improved selectivity and/or byproduct profiles than methods using conventional ODH or OCM catalysts.

摘要:
Improved catalysts including two-dimensional metal oxide species highly dispersed on a silica support are disclosed, as well methods of making and using such catalysts. The catalysts are substantially free of metal oxide nanoparticles. The higher than expected maximum dispersion densities are obtained in the catalysts by introducing dispersion-promoting sodium ions, and optionally, aluminum ions, onto the silica support. The improved catalysts may be used in a variety of chemical processes, including, without limitation, in dehydrogenation, oxidation, and metathesis reactions.
