Chemical cycle for thermochemical production of hydrogen from water. [reaction of chronic oxide with an alkali metal hydroxide]
Patent
·
OSTI ID:7278035
Hydrogen is produced by a closed cyclic process involving the reaction of chromic oxide with an alkali metal hydroxide to produce hydrogen, water and an alkali metal hypochromate as reaction products. The hypochromate is converted to the chromate by reaction with water to also produce the beginning chromic oxide and alkali metal hydroxide. The cycle is completed by reacting the thus formed chromate with the excess alkali metal hydroxide at a higher temperature to produce hypochromate water and oxygen. 4 claims, 1 drawing figure.
