A method of removing sulfur compounds from a hydrocarbon fluid. The method includes contacting the hydrocarbon fluid with an adsorbent comprising a carbonaceous material doped with nanoparticles of uranyl oxide (UO.sub.3) to reduce the concentrations of the sulfur compounds. The carbonaceous material is at least one selected from the group consisting of activated carbon and carbon nanotubes, and the adsorbent has a weight ratio of C to U in the range from 9:1 to 17:1, and a weight ratio of C to O in the range from 5:1 to 13:1.

Alumina/NiO/ZnO and Alumina/ZnO are synthesized via a novel modified hydrothermal method and investigated for the desulfurization activities. Sulfur compounds such as thiophene, benzothiophene (BT) and dibenzothiophene (DBT) are tested for their removal from model diesel fuel. The prepared composite materials were examined by the means of N.sub.2-adsorption, X-ray diffraction and Fourier transform infrared spectroscopy.
