Novel hydrotreating catalysts based on synthetic clay minerals

Saponites with Co, Ni, Zn, Mg and combinations of Co and Mg in the octahedral layer were synthesised. Their applicability as catalysts and supports for hydrotreating catalysts was investigated. The stability of these clays in a sulfidic environment was studied using Temperature Programmed Sulfidation. The catalytic performance of the saponites both bare and impregnated with Co/Mo was tested in the hydrodesulfurisation of thiophene.
