Process for the production of carbon nanoparticles and sequestration of carbon
Process for producing carbon nanospheres and other nano materials with carbon dioxide and magnesium. The carbon dioxide and magnesium are combusted together in a reactor to produce carbon nanospheres and magnesium oxide, which are then separated to provide the individual reaction products. The reaction occurs at a very high temperature, e.g. 2000° F.-5000° F. and also produces large amounts of useful energy in the form of heat and light, including infrared and ultraviolet radiation. Other oxidizing agents such as aluminum can be combined with the magnesium, and the metal oxides produced by the reaction can be recycled to provide additional oxidizing agents for combustion with the carbon dioxide. By varying the reaction temperature, the morphology of the carbon products can be controlled.
1. A process for producing a carbon product, comprising the steps of combusting carbon dioxide and magnesium together at a temperature of about 2000° F.-5000° F. to produce carbon nanoparticles, magnesium oxide, and heat and light energy, separating the carbon nanoparticles from the magnesium oxide and any other reaction products, and recovering the separated carbon nanoparticles.

9. A process for producing a carbon product, comprising the steps of reacting carbon dioxide with magnesium in a manner that produces a temperature of about 2000° F.-5000° F. to produce a carbon product, magnesium oxide, and heat and light energy, and separating the carbon product from the magnesium oxide and any other reaction products.
10. The process of claim 9 wherein at least some of the heat and light energy produced by the reaction is captured.

14. A process of producing carbon products and sequestering carbon, comprising the steps of: capturing carbon dioxide from emissions of fossil fuel combustion, combusting the carbon dioxide with magnesium to produce carbon particles and magnesium oxide, recovering magnesium from the magnesium oxide using heat from the magnesium-carbon dioxide reaction and/or power produced by a process that does not emit carbon dioxide, and combusting the recovered magnesium with the carbon dioxide, whereby the carbon dioxide emissions are captured and converted to carbon products without emitting carbon dioxide.
15. The process of claim 14 wherein the magnesium is recovered and recycled with power produced by solar energy or by wind energy.
