General description

4,6-Dimethyldibenzothiophene (4,6-DMDBT), a high refractory sulfur compound, is commonly found in diesel fuel. Its synthesis has been reported. The hydrodesulfurization of 4,6-DMDBT using bulk nickel alloy, bulk tungsten phosphide (WP), NiMo sulfide supported on active carbons and molecularly imprinted polymers have been reported. The dielectric behavior of 4,6-DMDBT under different microwave frequencies and temperature has been investigated.

In this work, the adsorption desulfurization performance and adsorption diffusion study of B2O3 modified Ag-CeOx/TiO2-SiO2 adsorbent were investigated. The adsorption desulfurization performance was studied by batch and fixed bed tests. The homogeneous surface diffusion model (HSDM) was employed to investigate
