    Citric acid-assisted synthesis of γ-alumina-supported high loading CoMo sulfide catalysts for the hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) reactions

    In the present work, the effect of the citric acid (i.e., adsorption-assisting agent) and the thermal treatment over the citric acid-synthesized CoMo catalyst precursors were investigated. The catalysts were p...
