  • Method and plant for chemical looping oxidation-reduction combustion of a gaseous hydrocarbon feedstock with in-situ catalytic reforming of the feed
    Patent number: 10473326
    Abstract: In a method and a plant for chemical looping oxidation-reduction combustion (CLC) of a gaseous hydrocarbon feed, for example natural gas essentially containing methane, catalytic reforming of the feed is performed within the reduction zone where combustion of the feed is conducted on contact with an oxidation-reduction active mass in form of particles. The reforming catalyst comes in form of untransported fluidized particles within the reduction zone. The catalyst thus confined in the reduction zone does not circulate in the CLC loop.

  • Chemical looping method for the combustion of heavy liquid hydrocarbon fractions
    Patent number: 9297528
    Abstract: The invention relates to a method for upgrading heavy liquid fractions resulting from oil refining, by combustion in a fluidized-bed chemical looping process. The method according to the invention allows energy to be produced by oxidizing totally the heavy liquid feeds while allowing direct capture of the CO2 emitted in the combustion fumes. The method according to the invention also allows a synthesis gas to be produced.
