Patent number: 10494257Abstract: 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.Type: GrantFiled: December 1, 2015Date of Patent: December 3, 2019Assignees: IFP ENERGIES NOUVELLES, TOTAL RAFFINAGE CHIMEInventors: Tiago Sozinho, Mahdi Yazdanpanah, Florent Guillou, Ann Cloupet, Stephane Bertholin, Hélène Stainton

Patent number: 10473326Abstract: 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.Type: GrantFiled: December 1, 2015Date of Patent: November 12, 2019Assignees: IFP ENERGIES NOUVELLES, TOTAL RAFFINAGE CHIMIEInventors: Mahdi Yazdanpanah, William Pelletant, Tiago Sozinho, Stephane Bertholin, Hélène Stainton, Ann Cloupet, Florent Guillou

Patent number: 10473325Abstract: 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).Type: GrantFiled: December 1, 2015Date of Patent: November 12, 2019Assignees: IFP ENERGIES NOUVELLES, TOTAL RAFFINAGE CHIMIEInventors: Florent Guillou, Beatrice Fischer, Tiago Sozinho, Ann Cloupet, Stephane Bertholin, Mahdi Yazdanpanah, Hélène Stainton

Patent number: 10184657Abstract: The invention relates to a process and to a unit for chemical looping oxidation-reduction combustion of a hydrocarbon feed, wherein heat exchanges are controlled through a level variation of a dense fluidized bed of active mass particles in an external heat exchanger (E1, E2), positioned on a transport line carrying particles circulating between a reduction zone (210) and an oxidation zone (200) for the particles in the chemical loop. The bed level variation is allowed through controlled application of a pressure drop on a fluidization gas outlet in the heat exchanger, said pressure drop being compensated by the level variation of an active mass particle bed in a reservoir zone provided on the particle circuit in the chemical loop.Type: GrantFiled: June 18, 2015Date of Patent: January 22, 2019Assignees: IFP ENERGIES NOUVELLES, TOTAL RAFFINAGE CHIMIEInventors: Mahdi Yazdanpanah, Thierry Gauthier, Florent Guillou
