In one embodiment, a process for the purification of COfrom chlorinated and non-chlorinated hydrocarbons, comprising: contacting a COstream with a metal oxide catalyst, wherein the stream comprises the COand impurities comprising the non-chlorinated hydrocarbons and the chlorinated hydrocarbons; interacting the impurities with the catalyst to form additional COand 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 COfrom chlorinated hydrocarbons and non-chlorinated hydrocarbons, comprising: contacting a COstream with a metal oxide catalyst, wherein the COstream comprises the COand impurities comprising the non-chlorinated hydrocarbons and the chlorinated hydrocarbons; oxidizing the impurities with catalyst oxygen to form additional COand converting the chlorine to metal chloride; and regenerating the catalyst by contacting the metal chloride with an oxygen containing gas stream.

Purification of carbon dioxide streams

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