| 简介 |
A method is discussed for handling and removing CO2 and/or producing carbon in powder form, especially nano carbon, and it is characterized by composite carbon-containing material being placed in a chamber and exposed to microwaves in order to produce plasma to then separate CO2 from plasma, as CO2-containing gases are fed to the chamber and led through the plasma zone, after which split elementary C and O are led out of the plasma zone directly to cooled surroundings where the temperature is below the threshold value for re-binding between carbon and oxygen (C and O). The invention relates to low temperature separation and thereby energy efficient cooling of separated elements produced in plasma, so that atomic carbon and oxygen (C and O) do not reconfigure outside of the plasma zone. The invention also relates to a composite material as well as the production of this, as well as a number of uses of the methods and the material. The invention is especially used in a process for removal of CO2, with simultaneous production of fine particular nano coal, as well as use for CO2-free hydrogen production of natural gas. |
