An impure stream of fuel gas is purified by passing the stream through a sorbent body which absorbs the impurities. The purified stream is then absorbed under pressure in a tank containing a suitable absorbent. The fuel gas is subsequently released to an internal combustion machine or other consumer of fuel gas for burning. The heated exhaust gases are flowed through the first purifying sorbent body to heat it and vaporize the unwanted impurities thus regenerating the sorbent body for a new cycle.
