The calcium oxide is then reacted with water to form calcium hydroxide and the calcium hydroxide is reacted with carbon monoxide to regenerate calcium formate and start the process over again. The process provides a convenient method for obtaining a mixture of hydrogen and carbon monoxide gases which are useful for many purposes. The carbon monoxide may be removed from the mixture of gases produced to obtain hydrogen which also finds many uses. Further, a mixture of hydrogen and carbon monoxide suitable for use in the Fischer-Tropsch reaction may be readily produced.Type: GrantFiled: July 23, 1976Date of Patent: May 2, 1978Assignee: The United States of America as represented by the Secretary of the NavyInventor: Russell Reed, Jr.
