Methods and apparatus for the pollution-free generation of electrochemical energy
Abstract
Abstract METHOD FOR APPARATUS FOR THE POLLUTION-FREE GENERATION OF ELECTROCHEMICAL ENERGY FROM COAL, HYDROCARBONS OR OTHER CARBONACHEMICAL FUELS BY A CYCLIC OPERATION WHEREIN A METAL SUCH AS LEAD IS OXIDIZED IN AN ELECTROCHEMICAL CELL DELIVERING ELECTROMOTIVE FORCE, WITH THE RESULTING LEAD ODIDE THEN BEING REDUCED IN A MOLTEN SALT MELT WITHIN A REGENERATION CHAMBER BY THE ADDITION THERETO OF THE FUEL. THE REDUCED LEAD METAL IS THEN RETURNED TO THE CELL FOR THE NEXT CYCLE. A USEFUL SALT MELT FOR EMPLOYMENT IN THE REGENERATION CHAMBER COMPRISES ADMIXED ALKALI METAL CARBONATES, AND PREFERABLY A MELT OF THIS CHARACTER IS EMPLOYED BOTH AS THE VEHICLE IN WHICH THE LEAD IS REDUCED BY THE FUEL AS WELL AS FOR THE ELECTROLYTE IN THE CELL. PASSAGE OF THE LEAD AND LEAD OXIDE BETWEEN THE RESPECTIVE CELL AND REGENERATION ZONES CAN BE CONTINUOUS OR INTERMITTENT. THE TOTAL OPERATION IS CAR-. RIED OUT WITHOUT FORMATION OF POLLUTANT GASES, AND ONLY CO2, (2 AND H2O VAPORS ARE VENTED. ANY SULFUR PRESENT IN THE FUEL IS CONVERTED TO LEAD SULFATE AND IS REMOVED FROM THE SALT, USUALLY BY TREATMENT OF A SIDESTREAM.
