摘要： 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.

摘要： The invention relates to a CLC plant for the combustion of solid hydrocarbon feedstocks generating particles of unburnt residues, comprising a solid/solid separator above the combustion reactor in order to efficiently separate the particles of the oxygen-carrying solid from the particles of unburnt residues contained in the gas/solid mixture (14) exiting from the combustion reactor. The chamber (1) of the solid/solid separator, the combustion reactor and the inlet (2) for the gas/solid mixture (14) of the chamber have a parallelepiped shape. The inlet (2) is equipped at its top with means (3) for distribution of said gas/solid mixture in the chamber which extend over the entire length of the inlet, improving the solid/solid separation.

摘要： The invention relates to a plant and to a method for chemical looping oxidation-reduction combustion of a gaseous hydrocarbon feed, for example natural gas essentially containing methane. According to the invention, catalytic pre-reforming of the feed is performed in a pre-reforming zone comprising a fixed reforming catalyst, while benefiting from a heat transfer between the reduction or oxidation zone of the chemical loop and the pre-reforming zone adjoining the reduction or oxidation zone. Pre-reforming zone (130) and oxidation zone (110) or pre-reforming zone (130) and reduction zone (120) are thus thermally integrated within the same reactor (100) while being separated by at least one thermally conductive separation wall (140).
