Abstract
The invention provides an adsorbent for removing sulfur from cracking gasoline or diesel fuel, which adsorbent comprises: (1) a carrier consisting of a source of silica, an inorganic oxide binder, and at least one oxide of metal selected from Groups IIB, VB and VIB; (2) at least one accelerant metal which is capable of reducing the sulfur in oxidized state to hydrogen sulfide and has a η<0.5, wherein η=(the amount in percentage of accelerant metal in crystal phase)/(the amount in percentage of accelerant metal in the adsorbent). The active components in the adsorbent can be evenly dispersed on the carrier in a matter close to monolayer dispersion, and which greatly improves the activity of the adsorbent. The preparation method and the use of the above adsorbent are provided.
