A process for the purification of pressurized gases, such as those emanating from the partial gasification resp. combustion of fuel, which gases contain Ni(CO).sub.4, which comprises contacting said Ni(O).sub.4 containing gas with a solvent at a temperature of from -60 to 0.degree. C., thereby forming a solution containing the gases and dissolved Ni(CO).sub.4, and thereafter heating said solution at a temperature of from 70 to 250.degree. C. for at least 0.25 hour at a pressure higher than the vapor pressure of said solvent, thereby precipitating and thereafter recovering nickel compound and releasing a purified solvent.
