Systems And Methods For Capturing, Isolating And Sequestering Carbon From Co2 In The Atmosphere In The Form Of Char Produced From Biomass Feedstock
US Patent:
2008031, Dec 25, 2008
Filed:
Jun 20, 2008
Appl. No.:
12/214688
Inventors:
Harry Vem Hall - Boise ID, US
Sheldon L. Schultz - Boise ID, US
Sheldon L. Schultz - Boise ID, US
International Classification:
C01B 31/20
US Classification:
4234371
Abstract:
The invention is a system and methods whereby biomass is gasified in a reactor vessel producing carbon char for the purpose of sequestering that char in soil, thereby reducing the carbon in the atmosphere. The invention relies on a renewable source for the biomass and a dedicated land area for sequestering the carbon char. The process in the reactor vessel is monitored and controlled to produce char with characteristics beneficial to the soil in which it is sequestered and to the plants growing in that soil. The net affect is “Carbon Negative.” The process returns only part of the carbon in the process feedstock to the atmosphere, thereby reducing atmospheric carbon dioxide in proportion to the amount of carbon char sequestered in the soil. The process produces a gas by product that may be burned for heat or used as a feedstock for other processes.
Method And Apparatus For Thermally Upgrading Carbonaceous Materials
US Patent:
7842107, Nov 30, 2010
Filed:
Jul 13, 2006
Appl. No.:
11/486349

Assignee:
Evergreen Energy Inc. - Denver CO
International Classification:
C10L 5/00
US Classification:
44629, 422200, 422201, 422307, 165110
Abstract:
Carbonaceous materials are thermally upgraded in a pressurized steam environment to remove moisture and other byproducts. A variety of water/solid separation devices may be employed in a process vessel to maximize moisture removal from the upgraded charge. Heating media inlet nozzles and process chamber vents are strategically positioned at the process vessel wall to minimize short circuiting of heating media to vessel outlet vents and to continuously separate hot water removed from the charge and condensed steam, such that the upgraded material removed from the process vessel is not discharged with accompanying free moisture. After upgrading, the charge may be rehydrated to improve its stability during shipping and storage.
