Abstract
An apparatus and process for graphite production from carbon dioxide. The process employs a plasma reactor assembly system providing conditions to convert carbon dioxide into graphite. The graphite output from the plasma reactor can be conveniently recovered in a solid recovery device. Any oxygen that is output from the plasma reactor may be subject to combustion and formation of additional carbon dioxide for cycling back into the plasma reactor.
Claims21
A method for converting carbon dioxide to graphite comprising:
- supplying a plasma reactor and introducing carbon dioxide into said plasma reactor at a pressure in the range of 1 bar to 80 bar;
- forming a plasma having a temperature of less than or 200 °C at an electron density in the range of about 1010 to 1020 electrons/cm3;
- and
- converting said carbon dioxide into graphite.
A method for converting carbon dioxide to graphite comprising:
- supplying a plasma reactor and introducing carbon dioxide into said plasma reactor at a pressure in the range of 1 bar to 80 bar;
- forming a plasma having a temperature of less than or 200 °C at an electron density in the range of about 1010 to 1020 electrons/cm3;
- converting said carbon dioxide into graphite;
- outputting said graphite to a solids recovery device along with oxygen which solids recovery device separates said graphite from said oxygen;
- said oxygen in said solids recovery device is directed to a combustor which forms carbon dioxide which carbon dioxide from said combustor is introduced into said plasma reactor.
A plasma apparatus for conversion of carbon dioxide to graphite comprising a compressor to deliver carbon dioxide to a plasma reactor at a pressure in the range of 1 bar to 80 bar, a plasma reactor that forms a plasma at a temperature of less than or equal to 200 °C at an electron density in the range of about 1010 to 1020 electrons/cm3 and wherein said plasma reactor converts carbon dioxide into graphite and wherein said plasma reactor outputs graphite to a solids recovery device that recovers solid graphite.
