PROCESS TO RECYCLE CARBON DIOXIDE CO2

摘要

The invention refers to a recycling process of a so-called gaseous flow (106) of CO2 essentially containing molecules of CO2, said process comprising the following steps:
heating of said gaseous flow of CO2 at a pyrolysis temperature of the material containing carbon (104);pyrolysis of a load of a carbon-containing material (104) containing elements of carbon by said gaseous flow, said pyrolysis reducing the molecules of CO2 by said elements of carbon to produce a first gaseous flow (110) essentially containing molecules of carbon monoxide (CO) at high temperature;oxidation of said molecules of carbon monoxide (CO) by elements of oxygen (O), said oxidation producing a second gaseous flow (114) essentially containing molecules of CO2;reduction of said molecules of CO2 of said second gaseous flow (114), said reduction supplying a third gaseous flow (120) essentially containing molecules of carbon monoxide (CO).;It also refers to a system to perform such a process.

主权项

1. A system to recycle an initial gaseous flow essentially containing carbon dioxide (CO2), said system comprising:
a mill to mill a load comprising a material containing carbon; a heat source for heating said initial gaseous flow at a pyrolysis temperature of the material containing carbon of the load comprising the material containing carbon; a first zone, or pyrolysis zone, for performing pyrolysis of the load comprising the material containing carbon by said initial gaseous flow at said pyrolysis temperature of the material containing carbon, said pyrolysis reducing said CO2 and producing a first gaseous flow comprising carbon monoxide (CO); a second zone, or oxidation zone, for performing oxidation of said CO, said oxidation producing a second gaseous flow containing CO2; and a third zone, or reduction zone, for performing reduction of said CO2 of said second gaseous flow, said reduction supplying a third gaseous flow comprising CO.
