Systems and methods for pyrolysis using an induction source of energy. A system can include: a reaction chamber, the reaction chamber having a cylindrical shape, the reaction chamber containing a catalyst; a fluidization plate connected to a first end of the reaction chamber; a gas input receiver connected to the fluidization plate; and a mechanism connected to a second end of the reaction chamber, wherein, during operation of the system: hydrocarbon gas is received at the gas input receiver; the input gas is forced through the fluidization plate; the fluidized gas mixes with the catalyst, resulting in at least one catalyzed molecule; the at least one catalyzed molecule undergo pyrolysis, resulting in at least two cracked elements; and the at least two cracked elements are removed from the system via the at least one output mechanism.

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.

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).

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.

A process for combusting coke from catalyst in partial burn mode is disclosed. The partial burn regenerator runs deprived of oxygen such that the flue gas will contain a fair amount of carbon monoxide. The oxygen present in the flue gas can burn in the bed before reaching the dilute phase. The catalyst distributor is positioned in the upper chamber of the regeneration vessel for discharging the catalyst.

The invention is a method for chemical looping (CLC) oxidation-reduction combustion of liquid hydrocarbon feedstocks carried out in a fluidized bed. A liquid hydrocarbon feedstock (2) is partly vaporized on contact with a hot particle solid (1) to form a partly vaporized liquid feedstock and to form coke on the solid prior to contacting partial vaporized liquid feedstock (19) with a redox active mass of particles (12) to achieve combustion of the partially vaporized liquid feed (19). The hot solid particles can notably be from a second fluidized-bed particle circulation loop.
