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