Process for removing heavy metals from process streams

A process for removing heavy metals from process fluids includes passing a heavy-metal-containing process fluid, including a reductant selected from hydrogen and carbon monoxide, at an inlet temperature 125° C. over a sorbent including (i) 4-75% by weight of one or more sulphided copper compounds se...

Beschreibung
Zusammenfassung:	A process for removing heavy metals from process fluids includes passing a heavy-metal-containing process fluid, including a reductant selected from hydrogen and carbon monoxide, at an inlet temperature 125° C. over a sorbent including (i) 4-75% by weight of one or more sulphided copper compounds selected from sulphided basic copper carbonate, sulphided copper hydroxide, sulphided copper oxide or mixtures of these, (ii) optionally a support material, and (iii) a binder and the binder content of the sorbent is in the range 5-30% by weight, wherein essentially all of the sulphided copper is in the form of CuS and the total metal sulphide content of the sorbent, other than copper sulphide, is 5% wt.
