•High surface area MgO supports.•Impregnation using MoO2- and Co- acetylacetonates solutions.•3.3-fold higher activities in hydrodesulfurization of benzothiophene.
The high surface area MgOs (330 and 500 m2 g−1) were studied as supports of Mo and CoMo hydrodesulfurization catalysts. New preparation methods based on impregnation of the supports with methanolic solution of MoO2- and Co- acetylacetonates or dimethylsulfoxide solutions of various Mo and Co compounds with chelating agent nitrilotriacetic acid (NTA) were compared with previously reported method methanol-assisted spreading. The most active CoMo/MgO catalysts exhibited 3.3-fold activities in hydrodesulfurization of benzothiophene as the reference industrial CoMo/Al2O3 catalyst.
