Gasoline desulfurization adsorbent and preparation method thereof

The invention provides a gasoline desulfurization adsorbent which is a copper modified ordered mesoporous carbon/silicon dioxide composite material. In the composite material, the mass percent content of carbon is 25-56% and the mass ratio of copper to the composite material is (0.08-0.18) to 1; the specific surface area of the composite material is 280-450m /g; the mesoporous pore diameter is 5-10nm; and the pore volume is 0.29-0.56cm /g. The invention further provides a preparation method of the gasoline desulfurization adsorbent. Phenolic resin and tetraethoxysilane are used as a carbon source and a silicon source and are commixed with a surfactant; an ordered mesoporous carbon/silicon dioxide composite material precursor is synthesized by adopting a solvent volatilization inducing self-assembling method; the precursor is treated by high temperature under an inert atmosphere to obtain the ordered mesoporous carbon/silicon dioxide composite material; and the copper component is loaded on the material by adopting an immersing method to obtain the gasoline desulfurization adsorbent. The gasoline desulfurization adsorbent has high selectivity on thiophene sulfide in gasoline.
