1. A process for reforming an oxygenated C,H-containing compound, the process comprising:
contacting the oxygenated C,H-containing compound with a catalyst in an aqueous solution, said aqueous solution comprising at least one CO2-precipitating cation,
wherein said oxygenated C,H-containing compound is reformed by reaction with H2O in said aqueous solution, to produce H2 and a precipitated carbonate form of generated CO2 and the CO2-precipitating cation,
the process further comprising adding, to a post-reforming reactor or post-reforming zone, positioned downstream of a respective reforming reactor or reforming zone in which at least about 90 wt-% of said oxygenated C,H-containing compound is reformed, a further amount of said at least one CO2-precipitating cation.
