Abstract
For removing mercury and any arsenic in hydrocarbon charges containing mercury and sulfur, the charge is contacted with an arsenic collecting material having catalytic properties ("catalyst") in hydrogen, the material containing at least one metal selected from the group consisting of nickel, cobalt, iron, palladium, and platinum; at least one metal selected from the group consisting of chromium, molybdenum, tungsten, and uranium; and an active phase carrier. Downstream of the catalyst or mixed therewith is a mercury collecting material containing a sulfide of at least one metal selected from the group consisting of copper, iron, and silver or sulfur, and an active phase carrier.
