TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compound: C(i) comprises Mo. C(ii) comprises cobalt (Co) and/or nickel (Ni). C(ii) further comprises rhenium (Re), ruthenium (Ru), rhodium (Rh), iridium (Ir), zinc (Zn), gallium (Ga), indium (In), germanium (Ge), tin (Sn), lanthanum (La), and/or samarium (Sm). C(iii) comprises lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and/or cesium (Cs). The compound C(i) is heptamolybdate ammonium or ammonium metatungstate. The compound C(ii) is a nitrate, chloride, carbonate, or acetate. The compound C(iii) is a carbonate, hydroxy-carbonate, acetate, acetylacetonate, citrate, nitrate, or chloride. Preferred Method: Sulfuration is performed by exposing the solid to a gas stream comprising a sulfur compound. The sulfur compound is selected from a compound of formula R1R2S, where R1 and R2 can be the same or different and are selected from hydrogen, 1-6C or aryl, thiophenes, mercaptans, or carbonyl sulfide. The gas stream further comprises a gas selected from H2, N2, noble gas, or synthetic gas. The molar ratio of sulfur compound in the gas stream is 1-85%, preferably 6-20%. The sulfuration temperature is 200-750 degrees C, preferably 300-600 degrees C. The molar ratio x is 0.2-2. At least 60% molar of C(ii) is selected from Co or Ni. The molar ratio y is 0.1-4, preferably 0.3-1.5. The solid comprising C(i)C(ii)xC(iii)y further comprises carbon or nitrogen. The ratio of carbon moles and the moles of C(i) is less than 3. The solid comprising C(i)C(ii)xC(iii)y is obtained by activation, preferably by a heat treatment of a precursor comprising a compound C(i), a compound C(ii), and compound C(iii). Activation is performed at a temperature of 200-700 degrees C, preferably 250-550 degrees C. It is also performed under a stream of sulfur-free gas. The gas stream comprises air, N2, noble gas, H2, or synthetic gas. Obtaining solid comprising C(i)C(ii)xC(iii)y comprises: (a) combining and reacting a compound C(i) with a compound C(ii) to obtain a solid; and (b) incorporating the solid to a compound C(iii). Combining and reacting are performed in aqueous medium, where the solid is obtained by precipitation and separated. Precipitation is performed by adjusting the temperature, pH, and/or volume. Combining and reacting comprises adjusting the temperature and pH of an aqueous solution of compound C(i) before its combination with compound C(ii). The pH is adjusted to 8-13. The pH adjustment is performed by the addition of a compound selected from ammonia, ammonium hydroxide, organic amines, or compounds that thermally decompose giving off ammonia. Combining and reacting are performed at a temperature of 50-120 degrees C. A support in step (a) is also suspended in a liquid medium, where the support suspended is metal carbide, oxide, or carbon. The oxide is selected from silicon dioxide (SiO2), titanium(IV) oxide (TiO2), aluminum oxide (Al2O3), zirconium oxide (ZrO2), or an oxide of a lanthanide element. The addition of compound C(iii) in (b) is performed by impregnating the solid in an aqueous solution of one or more precursor salts of C(iii). It is also performed by mixing the solid with compound C(iii). EXAMPLE - No suitable example given.
