ABSTRACT:
In a process for the production of hydrogen-rich gas from a gas containing hydrogen, carbon monoxide, carbon dioxide and other components by contacting the gas in a formate synthesis zone with an aqueous solution containing alkali metal carbonate and/or bicarbonate under conditions effective to produce an effluent aqueous solution containing the corresponding formate and an effluent gas containing the other components of the gas, and thereafter catalytically decomposing the formate in a formate decomposition zone under conditions effective to produce a hydrogen-rich gas and an aqueous solution which contains alkali metal carbonate and/or bicarbonate, the improvement comprising further contacting the gas and the aqueous solution in a catalytic formate synthesis zone prior to decomposing the formate.
