PURIFICATION OF CARBON DIOXIDE STREAMS |
摘要 |
In one embodiment, a process for the purification of CO2 from chlorinated and non-chlorinated hydrocarbons, comprising: contacting a CO2 stream with a metal oxide catalyst, wherein the stream comprises the CO2 and impurities comprising the non-chlorinated hydrocarbons and the chlorinated hydrocarbons; interacting the impurities with the catalyst to form additional CO2 and metal chloride; and regenerating the catalyst by contacting the metal chloride with an oxygen containing gas stream. In another embodiment, a process for the purification of CO2 from chlorinated hydrocarbons and non-chlorinated hydrocarbons, comprising: contacting a CO2 stream with a metal oxide catalyst, wherein the CO2 stream comprises the CO2 and impurities comprising the non-chlorinated hydrocarbons and the chlorinated hydrocarbons; oxidizing the impurities with catalyst oxygen to form additional CO2 and converting the chlorine to metal chloride; and regenerating the catalyst by contacting the metal chloride with an oxygen containing gas stream. |
