摘要： 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.

摘要： Desulphurization process for feedstocks in which the sulphur compounds contained therein are first separated into a concentrate stream which is then hydro-desulphurized, and the resulting hydrogen suphide removed using conventional sulphur removal techniques. The initial separation is preferably effected using membrane separation or temperature swing absorption processes.

摘要： Agglomerates containing oxide, hydroxides, carbonates and/or basic carbonates of copper, and zinc and/or another element such as aluminium or silicon, are useful for removal of sulphur compounds from fluids, especially under non-reducing conditions. The agglomerates have surface area above 80 m.sup.2.g.sup.-1 and a calcined density below 1.5 g.cm.sup.-3. After ignition, the cupric oxide plus zinc oxide (if any) content of the agglomerates is at least 70% w/w. The proportion of the copper compound is such that the copper atoms constitute 30-97% of the total of the copper, zinc, and said other element atoms in the agglomerates.
