Abstract
Method of removing a contaminant, such as arsenic or selenium, from a synthetic hydrocarbonaceous fluid comprising providing a guard bed having a plurality of sections, a first section having from about 10 to about 75 percent of its volume occupied by a contaminant-removing material comprising, alone or on a carrier, either iron, cobalt, nickel, oxides or sulfides of these metals, or combinations thereof; the remainder being inert material. A second section of the guard bed has a major portion of its volume occupied by the contaminant-removing material. The feed oil, in the presence of hydrogen is contacted with the particles in the respective sections of the guard bed.
