摘要：
In the present paper, we report a new method of HDS catalysts preparation which allows the deposition of high metal loadings on alumina by using ethylenediamine (En) in the impregnating solution. We have shown that the use of En improves the dispersion of Mo as well dispersed oxomolybdenum entities in the oxidic precursor. The promotor (Co or Ni) can be introduced in the Mo impregnating solution. A complete study of the mechanism of adsorption on alumina in the presence of this complexing agent has been undertaken and we report the comparison between Co-Mo-alumina and Ni-Mo-alumina catalysts from physical characterizations as well as from thiophene HDS data.
