Abstract
The present invention provides an adsorbent for removing sulfur from cracking gasoline or diesel fuel. The adsorbent has excellent abrasion-resistance and desulfurization activity. The adsorbent comprises from about 5 to about 35 wt % of alumina, from about 3 to about 30 wt % of silica, from about 10 to about 80 wt % of at least one oxide of metal selected from Groups IIB and VB, from about 3 to about 30 wt % of at least one metal accelerant selected from Groups VIIB and VIII, and from about 0.5 to about 10 wt % of at least one oxide of metal selected from Groups IA and IIA, based on the total weight of the adsorbent.
