  • Redox catalysts for the oxidative cracking of hydrocarbons, methods of making, and methods of use thereof
    Patent number: 11883800
    Abstract: A variety of redox catalysts, methods of making, and methods of using thereof are provided. Surface modified redox catalysts are provided having an oxygen carrier core with an outer surface that has been modified to enhance the selectivity of the redox catalyst for oxidative dehydrogenation. The surface modification can include forming a redox catalyst outer layer on the outer surface and/or suppressing sites that form nonselective electrophilic oxygen sites on the outer surface of the oxygen carrier. A variety of methods are provided for making the surface modified redox catalysts, e.g. modified Pechini methods. A variety of methods are provided for using the catalysts for oxidative cracking of light paraffins. Methods are provided for oxidative cracking of light paraffins by contacting the paraffin with a core-shell redox catalyst described herein to convert the paraffins to water and olefins, diolefins, or a combination thereof.
    Type: Grant
