  • Purification of a hydrocarbon mixture
    Patent number: 4894210
    Abstract: Desulphurization of saturated or near saturated gaseous hydrocarbon stream is effected using a bed of a particulate adsorbent comprising zinc oxide. Condensation of the higher boiling components is avoided by heating the raw gas to a temperature at least 10.degree. C. above its dew point. This heating is effected by heat exchange with the heated desulphurized gas and by heat exchange with the combustion products of a minor part stream taken from the raw gas and/or from the desulphurized product gas stream. The absorbent particles preferably have a high BET surface area and pore volume.
