 Preparation of nano-NiMoS catalyst.
 As an illustrative example, the nano-NiMoS catalyst can be prepared as follows: 2.466 grams of ammonium heptamolybdate, 2.000 grams of ethylenediammonium tetraacetic acid, 2.630 grams of nickel nitrate, 1.000 grams of S 8 Added to 60 ml of ethylene glycol solution, the formed slurry was heated to 120°C under nitrogen protection and vigorous stirring, and kept at this temperature for 10 hours, and the obtained black precipitate was washed, dried and vulcanized to obtain Nano sulfide catalyst A.
 Same as Example 1, except that the reaction temperature is 150° C., and the obtained nano-sulfide catalyst is marked as B.
 Same as Example 1, except that the reaction temperature is 210° C., and the obtained nano-sulfide catalyst is marked as C.
