The adsorbent of Cu-β/SBA-15 was synthesized by the impregnation method，and the samples were characterized by means of XRD，N2 adsorption-desorption，NH3-TPD，Py-FTIRThe results indicated that Cu-β/SBA-15 could retain the micro-mesoporous composite structure and has a good weak acidity.Using the β/SBA-15 as adsorbent，the static reaction of adsorption removal dibenzothiophene in a bath micro-reactor.The influences of reaction temperature、reaction time and reagent oil mass ratio to oil on adsorption capacity were investigated.Morever，experimental study of adsorption kinetics was performed.The results showed that the desulfurization rate of simulated diesel oil was 54.62% and the adsorption capacity was 2.27 mg/g at the reaction temperature of 120 ℃，reaction time of 120 min and reagent oil mass ratio of 1:30.In the initial stage of Cu-β/SBA-15 adsorption to dibenzothiophene，the pseudo-second-order kinetics equation and Elovich equation could well reflect the adsorption model.As well as，the correlation coefficient R2>0.99 in the entire stage，and the calculated equilibrium adsorption capacity qe=2.54 mg/g and the difference between the observed equilibrium adsorption capacity was 2.27 mg/g，which indicated that the pseudo-second-order kinetics equation could be more comprehensively describe the adsorption process of Cu-β/SBA-15 to dibenzothiophene and its controlled by both film diffusion and particle diffusion.
