Activated carbon based adsorbent carrying acid for eliminating mercury or mercury compounds contained in hydrocarbons wherein the activated carbon base is preferably provided with a micropore volume having radii less than 8 angstroms at more than 80 ml/g and wherein the acid carried on the activated carbon is preferably hydrochloric acid, sulfuric acid, or phosphoric acid, with hydrochloric acid being the most prefered. The active carbon base is preferably manufactured by activating a carbonaceous material in an atmosphere comprising water vapor of less than 30 vol. %. The subject adsorbent is applicable to eliminate mercury or mercury compounds contained in hydrocarbons by contacting them in liquid phase. The hydrocarbons are naphtha and intermediates of oil products or petrochemical products. This method features scarce desorption of carried acid and is useful to treat such hydrocarbons to prevent possible harmful amalgamation due to mercury in oil industry. |
