Support effect on the formation of catalytic site precursors in the thiophene hydrodesulfurization


The TiO2 and Al2O3 supported FeMo catalysts (6 and 12 wt.% Mo) have been prepared using (NH4)3Fe(OH)6Mo6O18 salt (FeMo6). They have been studied by the IR, TPR, XPS and MS methods and tested in thiophene conversion. The initial salt transforms in analog of the TiMo acid anion on the titania support and alumina heteropolymolybdate anion on the alumina support. Higher thiophene conversion is observed on the TiO2 supported catalysts.
