This invention provides for the removal of mercury from a mixture of saturated and unsaturated hydrocarbons such as from cracked gas. The gas first is contained in a regenerable adsorbent bed that removes water and mercury and then the regenerant stream for the adsorbent bed is passed through a nonregenerable bed comprising copper sulfide to trap the mercury. Surprisingly, it was found that acetylene within the regenerant stream does not react with the copper sulfide to produce explosive copper acetylides.
