    摘要： 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.

    摘要： The process has as an object the regeneration catalysts containing at least one contaminating metal of the vanadium, nickel and iron group. The operation is conducted as follows:(a) The catalyst (1) is roasted in the presence of an oxygen-containing gas so as to remove at least 90% of the sulfur;(b) The catalyst obtained in step (a) is contacted with a hydrogen peroxide aqueous solution containing at least one organic compound including a polar functional group, so as to remove at least 10% of the deposited metals of the vanadium, nickel and iron group; and(c) The regenerated catalyst (11) is separated from the aqueous solution of metal ions (5). The latter can be regenerated by passage over a complexing resin (6).The process is applicable to the regerneration of used catalysts, particularly to hydrotreatment catalysts in the oil industry.
