Synthesis of unsupported Ni–W–S hydrotreating catalysts from the oxothiosalt (NH4)2WO2S2

Synthetic routes for the preparation of unsupported Ni-W-S hydrotreating catalysts were studied. In the preparations studied, amorphous tungsten oxysulfide WOxSy was used obtained from the acid condensation or thermal decomposition of (NH4)2WO2S2 salt. Amorphous WOxSy solid was promoted by nickel sa...
