Patent number: 10450661Abstract: A method for using an electrochemical cell to continuously acidify alkaline water sources and recover carbon dioxide with simultaneous continuous hydrogen gas production. The electrochemical cell has a center compartment, an electrolyte-free anode compartment having a mesh anode in direct contact with an ion permeable membrane, an endblock in direct contact with the anode where the endblock provides a gas escape route behind the anode, an electrolyte-free cathode compartment having a mesh cathode in direct contact with an ion permeable membrane, and an endblock in direct contact with the cathode where the endblock provides a gas escape route behind the cathode. Current applied to the electrochemical cell for generating hydrogen gas also lowers the pH of the alkaline water to produce carbon dioxide with no additional current or power.Type: GrantFiled: June 6, 2017Date of Patent: October 22, 2019Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Felice DiMascio, Heather D.

Publication number: 20190085472Abstract: A method for the controlled removal of bicarbonate from alkaline water and its replacement with a strong base that is capable of chemically absorbing CO2 from the atmosphere as a carbonate and bicarbonate solution. This bicarbonate and carbonate solution is reprocessed in the central compartment of an electrolytic cation exchange module (E-CEM) to take advantage of the removal of CO2 from the air, and as an energetic byproduct of E-CEM dihydrogen production, and to regenerate the original strong base absorbent solution. Thus, this process is cyclical in nature, and no chemicals are needed except an initial source of alkaline water.Type: ApplicationFiled: July 26, 2018Publication date: March 21, 2019Inventors: Heather D.

Patent number: 10046990Abstract: The invention is directed to an apparatus and methods of its use to generate chlorine dioxide. The apparatus comprises three cation exchange resin chambers in fluidic communication to convert chlorite salt into chlorine dioxide. Unlike previous converters, the invention utilizes an novel method of acidifying some of the chlorite to produce a more effective process. The invention can achieve a 100% theoretical yield which is s significant improvement over the 80% theoretical yield in previous attempts using non-acidifying chemistry. The method also avoids the need for expensive catalysts.Type: GrantFiled: June 6, 2011Date of Patent: August 14, 2018Assignee: Ecolab USA Inc.Inventor: Felice DiMascio
