ABSTRACT:
In a process for the production of hydrogen-rich gas from a fuel gas containing carbon monoxide and other components, the fuel gas is contacted in a formate synthesis zone with an aqueous solution containing sodium or potassium carbonate and/or bicarbonate under conditions effective to produce an effluent aqueous solution of the corresponding formate and an effluent gas containing the other components of the fuel gas. The aqueous formate solution is thereafter subjected to catalytic decomposition in a formate decomposition zone under conditions effective to produce a hydrogen-rich gas and an aqueous solution which consists essentially of carbonate and/or bicarbonate solution.
