    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: A catalyst for the steam dealkylation of aromatic hydrocarbons, comprising a carrier and 3 metals, is regenerated in the reaction zone containing the catalyst bed, after disconnection of said zone from the producing unit, by proceeding to the successive steps of: scavenging said zone with hydrogen and then with an inert gas, progressively replacing said inert gas by a gas containing molecular oxygen, burning the catalyst at a temperature lower than 650.degree. C. so as to calcine the carbon deposits of the catalyst, passing through the catalyst bed an air stream containing halogen to increase the halogen content of the catalyst, calcining by means of an air stream at a temperature of 300.degree.-600.degree. C. and purging with an inert gas before reconnecting said reaction zone to the producing unit.
