| Abstract: | A newly developed PbMo/Al2O3 HDS catalyst shows activity and stability that are comparable to or better than the traditional CoMo/Al2O3. Activity is optimum when the atomic ratio Pb Mo is 16. At that ratio, the generated surface phase(s) display maximum degree of Mo coordinative unsaturation, as measured by low temperature oxygen chemisorption. |
