Abstract
Hydrodesulfurization/hydrodenitrogenation catalysts and a process for making these is disclosed. The catalysts have (i) overall stoichiometries of M.sub.2x A.sub.1-x S.sub.2, where 0.001.ltoreq.x.ltoreq.0.5, M is Co, Fe, Ni, Cu, Zn, Mn or Ru, and A is Mo or W, or (ii) overall stoichiometries of AS.sub.2-y, where 0.01.ltoreq.y.ltoreq.1.00. To obtain the M.sub.2x A.sub.1-x S.sub.2 catalysts, elemental material M, elemental material A and elemental sulfur are combined in an amount of x moles of M and (1-x)/2 moles of A per mole of S and the mixture is then heated, in the absence of oxygen, to a temperature of from 200.degree. C. to 800.degree. C. for 1 hour to 1 week. To obtain the AS.sub.2-y catalysts, elemental material A and elemental sulfur are mixed in an amount of (2-y) moles of sulfur per mole of A, and a parallel process protocol is followed.
