| titleOfInvention | Method for producing tungsten-chromium-zinc composite sulfide optionally containing nickel and hydrogenation catalyst |
| abstract | Abstract: PROBLEM TO BE SOLVED: To provide a method for producing various metal sulfides and a hydrogenation catalyst as a hydrogenation catalyst having an ability to hydrogenate and open an aromatic ring. SOLUTION: An aqueous solution of ammonium thiotungstate is added to zinc hydroxychromate hydrate by W / (Zn + C). r) Tungsten-chromium-zinc, which is added in an atomic ratio of 0.003 or more and 0.05 or less, evaporates water while mixing and stirring to obtain a solid component, and reductively decomposes it. Method for producing composite sulfide. An aqueous solution of ammonium thiotungstate is added to zinc hydroxychromate hydrate at an atomic ratio of W / (Zn + Cr) of 0.003 or more, 0.05 or less, and further, an aqueous solution of a nickel salt is added in a range where the Ni / W atomic ratio is 1.0 or less, A method for producing a nickel-tungsten-chromium-zinc composite sulfide catalyst, comprising evaporating water while mixing and stirring to obtain a solid component, and subjecting the solid component to reductive decomposition. |
