[en] A process is described for removing traces of Po from hydrocarbons and particularly from natural gas condensates and other distilled hydrocarbons. The hydrocarbon is contacted with solid acidic material which may consist of activated charcoal, silica gel, alumino-silicate molecular sieve material, Fuller's earth, activated titanium dioxide, anhydrous CuSO₄, or a mixture of two or more of these materials of surface area at least 5 m²/g. Activated charcoal of surface area 500 to 2000 m²/g is preferred and may be in the form of column packing, the hydrocarbons being passed through the column at a rate of 5 to 10 column volumes per hour.
