Publication number: 20230407233Abstract: Reactor for processing biomass, e.g. into biochar or bio cokes, with a reactor enclosure (2) having a transport unit (5). In a first reactor section (6) first gas injectors (11) are positioned below the transport unit (5), and first oxidant injectors (12) are positioned above transport unit (5). In a second reactor section (7) second gas injectors (13) are positioned below the transport unit (5), and second oxidant injectors (14) are positioned above the transport unit (5). In a the third reactor section (8) third gas injectors (15) are provided below the transport unit (5). The first, second and third gas injectors (11, 13, 15) are further arranged to output a first, second, and third gas, respectively, each having a low oxygen content, and the first and second oxidant injectors (12, 14) are arranged to output an oxidizing gas only for providing radiation heat energy, using a control unit (20).Type: ApplicationFiled: November 9, 2021Publication date: December 21, 2023Applicant: Nederlandse Organisatie voor toegepast -natuurwetenschappelijk Onderzoek TNOInventors: Christiaan Martinus van der Meijden, Hendrica Johanna Maria Visser

Patent number: 8821153Abstract: Method and system for the production of a combustible gas from a fuel, comprising the conversion of the fuel, at a temperature that is between 600 and 1000° C. and at a pressure that is lower than 10 bar, into at least a combustible gas that comprises CH4, CO, H2, CO2, H2O and higher hydrocarbons in a reactor installation (1). At least part of the higher hydrocarbons present in the combustible gas is catalytically converted into at least CH4, CO, H2, CO2 and H2O in a reactor (45) at a pressure that is lower than 10 bar. After this catalytic conversion, an amount of H2O and an amount of CO2 are removed from the combustible gas in a separator installation (50) at a pressure that is lower than 10 bar. After the removal of H2O and CO2, the pressure of the combustible gas is raised by a compressor (71).Type: GrantFiled: April 14, 2010Date of Patent: September 2, 2014Assignee: Stichting Energieonderzoek Centrum NederlandInventors: Christiaan Martinus Van Der Meijden, Lucas Petrus Loduvicus Maria Rabou

Patent number: 8603202Abstract: A device for producing a product gas from biomass includes a reactor which is delimited by a base part and reactor walls. The reactor walls include a circumferential wall and an upper wall. The reactor includes a supply opening for the supplying of biomass, and also at least one riser for the chemical conversion of supplied biomass to a product gas and a solid substance. The riser is attached within the circumferential wall and includes an upper end and a lower end. The reactor also has a discharge opening for the discharging of the product gas. The riser is fastened to at least one reactor wall. The base wall of the reactor has a through-opening through which the lower end of the riser movably extends.Type: GrantFiled: September 5, 2006Date of Patent: December 10, 2013Assignee: Stichting Energieonderzoek Centrum NederlandInventors: Christiaan Martinus van der Meijden, Abraham van der Drift
