Effects of support on the properties of light fuel hydrodesulfurization catalyst

This research reviews the effects of the single component, the mixed oxides and the mesoporous materials on catalyst. Titanium dioxide and zirconium dioxide as single component support show higher activity than alumina in hydrodesulfurization, but their specific surface area need be increased further. Compared with the single component, the mixed oxides with higher specific surface area and strength can improve hydrodesulphurization activity. It is pointed out that mesoporous materials with higher specific surface area, larger pore diameter, narrower pore size distribution and longer-range ordered pore, are advantaged to other supports in hydrodesulphurization of the large molecule substance such as aromatic sulfides.
