Abstract: 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).

Abstract: 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.

Abstract: The invention relates to a method and to a plant for chemical looping oxidation-reduction combustion (CLC) of a gaseous hydrocarbon feed, for example natural gas essentially containing methane. According to the invention, catalytic steam reforming of the feed is performed between two successive feed combustion steps on contact with an oxidation-reduction active mass in form of particles. The reforming catalyst is arranged in a fixed bed in an intermediate reforming zone (130) between the two reduction zones (120, 140) where the two combustion steps are conducted.FIG. 2 to be published.

Abstract: The present invention relates to a cyclone for gas/solid separation in a plant for chemical looping combustion of a hydrocarbon feedstock using reactors operating as circulating fluidized beds. The novel cyclone has a specific inlet pipe of which a lower wall and one of the lateral walls are inclined and which has at least one auxiliary-gas injection means at the lower wall, making it possible to reduce the deposition of solid matter at the inlet of the cyclone, to optionally carry out chemical reactions inside the cyclone, and to improve the efficiency of the cyclone.
