Abstract
All transition metals in the first, second, third rows and some in the fourth row, supported on carbon at low concentration, have been tested in their sulfided form to evaluate their activity toward the hydrodesulfurization (HDS) reaction at four different temperatures. The first row shows two maxima on V Cr and Co whatever the temperature with two orders of magnitude between the lowest and the highest activities (one order between Ni and Co). The second and third rows present a single maximum on Rh and Ir, respectively, with three orders of magnitude between the lowest and the highest activities. Electronic considerations have been proposed (S. Harris and R.R. Chianelli, J. Catal., 86, 400, 1984) to account for these different activities. A new complementary approach is developed by introducing the structural properties of the Sulfides.
