ABSTRACT:
A process for adsorptive desulfurization of gasoline or diesel oil or aromatics lower than C12containing organic sulfide impurities, wherein these feedstocks contact an amorphous alloy adsorbent comprising nickel as a major active component in a fluidized bed reactor or a magnetic-stabilized fluidized bed reactor or a slurry bed reactor. There is only a single diffuse peak at 2θ=45° in the 2θ range from 20° to 80° in the X-ray diffraction (XRD) pattern of the adsorbent. The adsorbent consists of 50-95 wt % of nickel, 1-30 wt % of aluminum, 0-35 wt % of iron, and 0-10 wt % of one or more metals selected from copper, zinc, molybdenum, chromium, and cobalt.
