    • The invention concerns a fixed bed process for capturing arsenic and for desulphurizing a hydrocarbon fraction comprising olefins, sulphur and arsenic, said process comprising a step a) for bringing a capture mass into contact with said hydrocarbon fraction in the presence of hydrogen, the ratio between the flow rate of hydrogen and the flow rate of the hydrocarbon fraction being in the range 50 to 800 Nm3/m3, the operating temperature being in the range 200° C. to 400° C., the operating pressure being in the range 0.2 to 5 MPa. The capture mass comprises molybdenum in a sulphurized form, nickel in a sulphurized form and at least one porous support selected from the group constituted by aluminas, silica, silica-aluminas, titanium oxide and magnesium oxide. The nickel content is in the range 10% to 28% by weight and the molybdenum content is in the range 0.3% to 2.1% by weight.
    • 本发明涉及用于捕获砷和用于脱硫包含烯烃,硫和砷的烃馏分的固定床方法,所述方法包括步骤a)使捕获物质在氢气存在下与所述烃馏分接触, 氢气的流量和烃馏分的流量在50至800Nm 3 / m 3的范围内,操作温度在200℃至400℃的范围内,操作压力在0.2至 5MPa。 捕获质量包括硫化形式的钼,硫化形式的镍和至少一种选自氧化铝,二氧化硅,二氧化硅 - 氧化铝,氧化钛和氧化镁的多孔载体。 镍含量为10〜28重量%,钼含量为0.3〜2.1重量%。
