A process for the purification of CO2 from chlorinated hydrocarbons and non-chlorinated hydrocarbons, comprising: contacting a CO2 stream with a chromium oxide catalyst, wherein the stream comprises the CO2, and impurities, wherein the impurities comprise the non-chlorinated hydrocarbons and the chlorinated hydrocarbons; forming a purified CO2 stream by interacting the impurities with the chromium oxide catalyst to form additional CO2 and chromium chloride; and regenerating the chromium oxide catalyst by contacting the chromium chloride with an oxygen containing gas stream.
