Patent number: 11891572Abstract: A method for producing a pyrolysis oil is described. In said method, a feedstock to be treated is first pyrolyzed in a pyrolysis zone, in which the feedstock is heated to a temperature of 250 degrees Celsius to 700 degrees Celsius; and pyrolyzed solids and pyrolysis vapors are formed. The pyrolysis vapors are then reformed at a temperature of 450 degrees Celsius to 1,200 degrees Celsius in a post-conditioning zone, in which the pyrolysis vapors are brought into contact with a catalyst bed, wherein the pyrolysis oil is formed. In this case, the catalyst comprises a pyrolyzed solid, which can be obtained according to the pyrolysis, described above. Finally the pyrolysis oil is separated from the additional pyrolysis products, which are formed, in a separation unit.Type: GrantFiled: June 24, 2021Date of Patent: February 6, 2024Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Andreas Hornung, Andreas Apfelbacher, Miloud Ouadi, Johannes Neumann

Patent number: 10414987Abstract: Systems and methods for thermocatalytic treatment of material are provided. The system can have a charging region to supply starting material, a preconditioning zone in which preconditioned material is formed from the starting material, a pyrolysis zone in which pyrolyzed material is formed from the preconditioned material, and a separation unit for separation of the pyrolyzed material. In the preconditioning zone and the pyrolysis zone, a heater can be provided for heating of the material. Also provided in the pyrolysis zone are recirculation means with which a solid portion of the pyrolyzed material can be recirculated directly into the region of the pyrolysis zone facing toward the preconditioning zone.Type: GrantFiled: April 14, 2015Date of Patent: September 17, 2019Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Samir Binder, Michael Jakuttis, Andreas Apfelbacher, Andreas Hornung

Patent number: 9663733Abstract: A biomass pyrolysis process is provided in which biomass feedstock is mixed with a heat carrier. The heat carrier at least partly comprises char. The ratio by weight of biomass to char is in the range 1:1 to 1:20. The process may be carried out by in a screw/auger pyrolysis reactor in which the solid feedstock components are conveyed along the reactor by a first screw. A second screw conveys at least a portion of the solid products of the biomass pyrolysis back to a heat transfer medium input port. Thus, the heat transfer medium includes char from the biomass pyrolysis.Type: GrantFiled: July 23, 2014Date of Patent: May 30, 2017Assignee: Aston UniversityInventors: Andreas Hornung, Andreas Apfelbacher

Patent number: 8658414Abstract: A biomass processing system is disclosed, with an algae biomass growth container and a pyrolysis reactor for pyrolysis processing of the algae biomass. A conveying apparatus links the pyrolysis reactor and the biomass growth container for conveying at least part of at least one of the pyrolysis products from the reactor to the biomass growth container for promoting algae biomass growth. The pyrolysis product is a nutrient-rich aqueous phase produced directly or indirectly through pyrolysis processing to the biomass growth container, e.g. an aqueous phase derived from the vapor products of the pyrolysis, or a char wash obtained by washing the char product of the pyrolysis.Type: GrantFiled: May 13, 2009Date of Patent: February 25, 2014Assignee: Aston UniversityInventors: Andreas Hornung, Andreas Apfelbacher

Publication number: 20110278149Abstract: A biomass pyrolysis process in which biomass feedstock particles (having a d5o mean particle size of at least 1 mm) are thermally treated substantially in the absence of oxygen to pyrolyse the biomass feedstock particles. The thermal treatment of the biomass feedstock particles includes a heat treatment drying step at a temperature in the range 100° C. to 250° C. Then, at a pre-pyrolysis heating location in a heat treatment system, the biomass feedstock particles are heated to a temperature in the range 280° C. to 350° C., held within the same temperature range for a time of at least 5 seconds and then moved from the pre-pyrolysis heating location to a pyrolysis heating location by a conveyor system for heating to a temperature above 350° C. for pyrolysis.Type: ApplicationFiled: May 11, 2010Publication date: November 17, 2011Inventors: Andreas Hornung, Andreas Apfelbacher
