Abstract

Re2O7 catalysts supported on various carriers (Al2O3, SiO2 and activated carbon), with various rhenium loadings (between 0.01 and 2.5 at. nm-2), and after different heat treatments, at 380, 575 or 825 K, were subjected to a thiophene hydrodesulphurization test at 675 K. The catalysts were very active, viz. 2–20 times more active than molybdenum catalysts with a similar surface coverage. The activity of rhenium sulphides depended slightly on the support used and increased in the order SiO2
