The invention concerns a process for the elimination of mercury from hydrocarbons by passage of the feedstock with hydrogen over a catalyst then bringing the product obtained into contact with a mercury retention bed, the catalyst comprising at least one element selected from the group constituted by iron, nickel, cobalt, molybdenum, tungsten, palladium, wherein at least 5% is in the sulphide state. Any arsenic present in the feedstock is also eliminated. In accordance with the invention, the catalyst is simultaneously presulphurated and reduced. The invention results in a considerable reduction in operation period and high retention efficiency at temperatures between 120.degree. C. and 250.degree. C. and in the presence of 0-1000 mg of sulphur/kg of feed.

Process for the elimination of mercury from hydrocarbons by passage over

Process for the dehydrogenation of a charge incorporating saturated aliphatic hydrocarbons essentially having 3 to 5 carbon atoms per molecule, in which the charge, previously heated to the reaction temperature and without premixing with the hydrogen, is introduced at the inlet of at least one reactor, where the dehydrogenation reaction is performed in the presence of a catalyst, preferably incorporating a support having at least one oxide of an element chosen from among the groups IIA, IIB, IIIA, IIIB, IVA and IVB of the periodic classification of elements, at least one noble metal from the platinum family, at least one promotor metal and at least one alkali metal or alkaline earth metal.

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.
