Patent number: 9272255Abstract: The combustion device according to the invention produces gases containing CO2 and water vapor and comprises a circulating fluidized bed reaction chamber (1, 2), a separator (10, 20), heat recovery means of which a part is situated in a dense fluidized bed (12, 12a, 22), wherein the part located in the bed of the heat recovery system(s) is composed of catalyst tubes (120, 120a, 220) through which a gas mixture flows. The gas mixture is composed of natural gas and/or naphtha or refinery gas or two or more of these gases. The gas undergoes reformation which converts it into a synthesis gas containing hydrogen. The fact of the catalyst tubes being situated in the dense fluidized bed made up of ashes from the combustion allows the catalyst to be reheated in a homogenous manner and the reforming reaction of the natural gas mixture to be stimulated.Type: GrantFiled: March 29, 2006Date of Patent: March 1, 2016Assignee: ALSTOM Technology LtdInventors: Jean-Xavier Morin, Corinne Beal, Silvestre Suraniti

Patent number: 8171893Abstract: The boiler of the invention has a circulating fluidized bed, uses solid fuels and the oxygen obtained by high temperature oxygen production membranes, and is characterized in that the membranes are placed in the bed. These membranes are, for example, of the OTM (Oxygen Transport Membranes) type. Since the membranes operate at over 700° C., their positioning in the outer bed is ideally selected because the temperature of the solids circulating in the outer bed is between 750 and 900° C. This is particularly remarkable because the operating temperature windows of the circulating fluidized bed coincide with the optimal temperature window of use of the membranes.Type: GrantFiled: February 22, 2005Date of Patent: May 8, 2012Inventors: Jean-Xavier Morin, Corinne Beal, Silvestre Suraniti

Patent number: 7987993Abstract: A separator of solids for separating first and second solids, the diameter and density of the first solids being larger than the diameter and density of the second solids. A first substantially vertical internal baffle (2) forms a passage in the low portion of the separator and forms two compartments (1A, 1B) on the passage of the fluidized solids. The fluidization of each compartment is independently controlled by two fluidization gas inlets (3A, 3B) in order to obtain the desired velocity field for separating the first and second solids in the first compartment (1A) and discharging the second solids through a vent (8), as well as for transferring the first solids into the second compartment (1B).Type: GrantFiled: January 23, 2007Date of Patent: August 2, 2011Assignee: Alstom Technology Ltd.Inventors: Jean-Xavier Morin, Corinne Beal, Silvestre Suraniti
