The invention discloses a method for carrying out adsorption desulfurization on catalytically cracked gasoline. Catalytic gasoline subjected to selective hydrodesulfurization is taken as a raw material (with sulfur content being less than 150 micrograms/gram) and firstly is subjected to cutting fractionation through a fractionating tower to obtain light gasoline and heavy gasoline; then, the light gasoline enters a fixed bed reactor for non-hydroforming physical adsorption desulfurization, wherein the non-hydroforming physical adsorption desulfurization can not reduce the olefin content, so that the octane value of a product cannot be lost; and the heavy gasoline enters the fixed bed reactor for hydroforming adsorption desulfurization, and the reaction product and a light gasoline physical adsorption desulfurization product are blended to obtain a clean gasoline product which meets the requirement of Euro V sulfur index. The method disclosed by the invention can be combined with the traditional selective hydrodesulfurization process to produce the clean gasoline which meets the requirement of Euro V sulfur index and has the advantages of small equipment investment, convenience in adsorbent filling operation, easy operation and low octane value loss.
