Patent number: 10662386Abstract: A downdraft gasifier and method of gasification with high yield biochar that utilizes a plurality of high throughput, vertically positioned tubes to create a pyrolysis zone, an oxidation zone beneath the pyrolysis zone and a reduction zone beneath the oxidation zone. A rotating and vertically adjustable rotating grate is located beneath the reduction zone of the gasifier. In addition, a drying zone is located above the pyrolysis zone so the heat of the gasifier can be used to dry feedstock before it enters the gasifier. By optimizing the grate height and rpm, feedstock retention time in the drying zone, the drying zone temperature and feedstock moisture content, the result is gasification of biomass with a high yield and continuous biochar production.Type: GrantFiled: December 6, 2019Date of Patent: May 26, 2020Assignee: Aries Gasification, LLCInventors: Renus Kelfkens, Brandon Davis, Matthew Newman, Deon John Potgieter, Billy Freeman Hopper, Jeffrey Scott Brown, Mark Oliver Loftin

Patent number: 10465133Abstract: A downdraft gasifier that utilizes a plurality of vertically positioned tubes to create a pyrolysis zone, an oxidation zone beneath the pyrolysis zone and a reduction zone beneath the oxidation zone. The shape of the tubes eliminates the need for a restriction (hearth), which limits the maximum achievable throughput. A rotating and vertically adjustable grate is located beneath, but not attached to, the reduction zone of the gasifier.Type: GrantFiled: May 27, 2016Date of Patent: November 5, 2019Assignee: Aries Gasification, LLCInventors: Deon John Potgieter, Billy Freeman Hopper, Jeffrey Scott Brown, Mark Oliver Loftin

Patent number: 9976095Abstract: A device and method for cleaning producer gas includes a filter bed housing and a microwave chamber. The filter bed housing comprises an inlet for carbon-based material and a spent carbon outlet. The microwave chamber comprises a permeable top and wave guides around the perimeter through which microwaves can be introduced into the device using magnetrons. The method comprises using the device by filling the filter bed housing with carbon-based material, introducing microwaves into the microwave chamber using the magnetrons and wave guides, passing the gas through carbon-based material in the filter bed chamber, the microwave chamber, the gas permeable top and the gas outlet.Type: GrantFiled: January 29, 2016Date of Patent: May 22, 2018Assignee: Aries Gasification, LLCInventors: Deon John Potgieter, Mark Oliver Loftin, Tom Stanzione, Jeffrey Scott Brown

Patent number: 9279090Abstract: A device and method for cleaning producer gas includes a filter bed chamber, a microwave chamber, a first catalytic chamber and a second catalytic chamber. The filter bed chamber comprises an inlet for carbon-based material and a spent carbon outlet. The microwave chamber comprises a permeable top and wave guides around the perimeter through which microwaves can be introduced into the device using magnetrons. The first catalytic chamber is connected to the microwave chamber, and the second catalytic chamber is connected to the first catalytic chamber. The method comprises using the device by filling the filter bed chamber with carbon-based material, introducing microwaves into the microwave chamber using the magnetrons and wave guides, dissociating heavy carbons entrained within the gas by passing the gas through carbon-based material in the filter bed chamber, the microwave chamber, the first catalytic chamber and the second catalytic chamber.Type: GrantFiled: September 1, 2015Date of Patent: March 8, 2016Assignee: PHG ENERGY, LLCInventors: Deon John Potgieter, Mark Oliver Loftin, Tom Stanzione, Jeffrey Scott Brown
