ABSTRACT:
Calcium formate is heated to a temperature in the range of from 300.degree. to 400.degree. C to form calcium carbonate, hydrogen and carbon monoxide and the gases are bled off. The calcium carbonate is then heated to about 825.degree. C whereby calcium oxide and carbon dioxide are formed and the gas is again bled off. 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.
