Abstract
A mixed-solid solution tri-metallic oxide/sulfide catalyst having the formula: EQU M.sub.I O.sub.a S.sub.b.M.sub.II O.sub.c M.sub.III O.sub.d wherein M.sub.I is vanadium, neodymium, tantalum, chromium, molybdenum, tungsten, and mixtures thereof; O is oxygen; S is sulfur; a is selected from zero and a number up to a positive real number representing the stoichiometric requirement, and b is selected from zero and a number up to a positive real number representing the stoichiometric requirement, provided one of a and b is a positive real number; M.sub.II is titanium, zirconium, hafnium, and mixtures thereof; c is a positive real number up to the stoichiometric requirement; M.sub.III is lithium, sodium, potassium, rubidium, cesium, francium, beryllium, magnesium, calcium, strontium, barium, radium, zinc, cadmium, mercury, scandium, yttrium, lanthanum, actinium, and mixtures thereof; and d is a positive real number up to the stoichiometric requirement; and wherein M.sub.I O.sub.a S.sub.b is mixed in a solid solution of M.sub.II O.sub.c M.sub.III O.sub.d. A process for production of the above catalyst and its use in hydroforming reactions is taught.
