Abstract
The hydrodesulfurization of thiophene was studied over unsupported nic kel-neodymium bimetallic catalysts. The physical and chemical changes of bimetals were observed after calcination and presulfidation, respec tively. The activity was increased with addition of neodymium to nicke l catalysts and was in good correlation with the surface area of catal ysts. Qualitative evidence from XRD and SEM on the role of Nd as a str uctural promoter were provided.
