  • Publication number: 20200223692
    Abstract: A modified bed particles, related methods and applications in processes involving microwave-assisted catalytic reactions. The bed particles modified to be used as a microwave receptor that is capable to simultaneously sustain heat generation mechanisms under microwave irradiations and physically act as catalyst support. The bed particle comprises a dielectric coating deposited on an external surface of a core, the bed particle being sized for use in a fixed bed reactor or a fluidized bed reactor. The bed particles may further comprise a catalytically active material supported on a surface of the dielectric coating. Irradiating the gas-solid reactor with microwaves enables heating the dielectric coating of the solid bed particles, the dielectric coating locally transferring thermal energy to the surrounding gaseous reactants which are thereby selectively converted into the primary products.
