Abstract
Agglomerates containing oxides, hydroxides, carbonates and/or basic carbonates of copper, and zinc and/or another element such as aluminum 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.
