<p>PURPOSE:To selectively and effectively remove extremely small quantities of mercury in oil and facilitate separation of catalytic substance after the reaction, by bringing a hydrocarbon base oil containing mercury into contact with an adsorbent having copper on a carrier such as activated clay. CONSTITUTION:An adsorbent consisting of (A) one or more carrier selected from activated clay, silica gel, zeolite, molecular sieves, alumina, silica and silica alumina carrying preferably (B) 0.1-30wt.% copper, preferably including copper halide and a hydrocarbon base oil containing mercury are subjected to solid-liquid contact and mercury is removed. The surface area of the component A is preferably >=100m<2>/g (especially 100-1500m<2>/g).</p> |
