Abstract
In the present invention, a petroleum fraction containing arsenic is brought into contact with an adsorbent comprising a substrate such as an active carbon, bituminous coal or organic polymeric compound having introduced therein a sulfur element, particularly represented by mercapto moiety, and therefore arsenic in the petroleum fraction can be removed at a high percent removal by means of simple equipment, and, even if highly reactive olefins are contained in the petroleum fraction, these olefins do not polymerize, thus troubles do not occur.
