Abstract
Impregnation of oxidic precursor with thioglycolic acid aqueous solution was successfully used to improve the performances of thiophene hydrodesulfurization catalysts. Raman, EXAFS and XPS studies indicate that addition of this chelating agent affects the sulfidation of the supported metals. The higher catalytic performances were attributed to an optimization of the nature and morphology of the active phase obtained by the use of this chelating agent which permits a simultaneous sulfidation of both Co and Mo atoms.
