ABSTRACT:
A process is provided for producing halogen gas from gaseous or aqueous halogen acid, wherein the halogen is mixed with a slurry of electrocatalytically active particles and pumped into an electrochemical cell. The slurry of said particles is then electrochemically treated employing said slurry as a dispersed halogen electrode. Under the influence of an applied potential, halogen is released at the slurry electrode while protons migrate to the counterelectrode to form and release hydrogen gas. The process is particularly applicable to the production of chlorine from gaseous or aqueous hydrochloric acid using an aqueous slurry of circulating particulate carbon as the chlorine electrode.
Apparatus for carrying out the above process is also provided. The process can also be applied to the production of hydrochloric acid from chlorine and hydrogen.
