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 1∶6. At that ratio, the generated surface phase(s) display maximum degree of Mo coordinative unsaturation, as measured by low temperature oxygen chemisorption.
