Patent number: 9458397Abstract: A method and equipment for producing synthesis gas (S) from solid carbon particles (C), the carbon particles (C) being obtained by pyrolysis, gasification of the carbon particles (C) occurs by indirect heating of the carbon particles (C) in the presence of a process gas (P) in the same space where the carbon particles (C) are present, and the synthesis gas (S) generated during the gasification is discharged from the space. The method is characterised in that the carbon particles (C) and the process gas (P) are located in a reactor (1), and the indirect heating occurs by way of radiant heat from burners (Br1-Brn) located in the reactor (1).Type: GrantFiled: June 11, 2009Date of Patent: October 4, 2016Assignee: CORTUS ABInventor: Rolf Ljunggren

Patent number: 9309464Abstract: Method and equipment for producing coke (PC) during indirectly heated gasification, in which coal particles are supplied to a gasification reactor (1) and process gas (P) supplied during the gasification is reduced in it to synthesis gas (S), whereby the synthesis gas (S) is removed from the gasification reactor (1). The method is distinguished in that at the same time a gasification takes place, a coking of coal takes place in an inner reactor (4) arranged inside the gasification reactor (1), that the inner reactor (4) is indirectly heated, that coke (PC) and combustible gases are produced in the inner reactor (4) during the coking, and that the combustible gases are used for the indirect heating in the gasification in the gasification reactor (1).Type: GrantFiled: October 10, 2011Date of Patent: April 12, 2016Assignee: CORTUS ABInventor: Rolf Ljunggren

Patent number: 8932374Abstract: A method and equipment for producing hydrogen from biomass includes the stages of drying of the biomass, gasification of the biomass, and water gas shift reaction. The method further includes: subjecting the outgoing gases (CO2, N2 and H2O) from the gasification stage to a first heat exchange, wherein the outgoing gases are cooled; evaporating water with heat from outgoing gases; subjecting the steam to heat exchange wherein the steam is heated; reducing the steam to synthesis gas, wherein the synthesis gas is cooled and the air supply to the gasification is heated; separating the synthesis gas into a hydrogen stream and a carbon monoxide stream; reacting the carbon monoxide with water steam to carbon monoxide and hydrogen; separating also these secondary streams into a hydrogen stream and a carbon monoxide stream; and bringing together the primary and secondary hydrogen stream into a product stream.Type: GrantFiled: June 11, 2009Date of Patent: January 13, 2015Assignee: Cortus ABInventor: Rolf Ljunggren

Patent number: 8784688Abstract: Method and device for introducing pulverulent material (C) into a gasification reactor (2), wherein a process gas (P) supplied to a gasification reactor (2) is reduced to a synthesis gas (S) by the pulverulent material (C) and the pulverulent material (C) is introduced into the gasification reactor (2) via an inlet area, a negative pressure being generated in the inlet area for the pulverulent material (C) via a Laval nozzle (15) and the negative pressure being generated in that the process gas (P) passes through the Laval nozzle (15). The method is characterized in that the process gas (P) expands in a gasification space (5) in the gasification reactor (2).Type: GrantFiled: May 5, 2011Date of Patent: July 22, 2014Assignee: Cortus ABInventor: Rolf Ljunggren
