摘要： 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.

摘要： A process for the elimination of arsenic from hydrocarbons with a retention mass wherein the retention mass is pretreated before being brought into contact with the feedstock to be purified. The retention mass contains at least one element selected from the group formed by iron, nickel, cobalt, molybdenum, tungsten, palladium and chromium. At least 5% by weight of these element(s) are in the sulfide form. The pretreatment involves impregnation with a sulfur compound carried out simultaneously with reduction. The arsenic elimination process is carried out between 120.degree. C. and 250.degree. C. in the presence of 0-1000 mg of sulfur/kg of feedstock
