Beschreibung
Zusammenfassung:	A sorbent precursor is described comprising agglomerates of an inert particulate support material, the agglomerates being bound together with a binder comprising cement and/or clay, said binder being characterized as an agglomerate binder, wherein (a) the agglomerates are coated with a surface layer coating comprising a particulate copper compound and one or more coating binders, and (b) the surface layer has a thickness in a range of from 1 to 1000 μm. The sorbent precursor may be sulphided to prepare a sorbent for removing heavy metals from fluid streams.
