Synthesis Of Sulfur Containing Nickel Molybdenum Hydrotreating Catalyst Precursor System

The topic main research the diesel hydrodesulfurization catalyst prepara-tion. Choose ammonium tetrathiomolybdate as HDS catalyst active component, Ni as addi-tives, through experiments to explore Ni-Mo-S active synthetic conditions and structure of the precursor. Chose three kinds of organic acid nitrilotriacetic acid, edta, citric acid, organic acid ligand compounds more preparation of Ni or Mo-organic acid ligand compounds. To explore the different organic ligands for the influence of the complexes formed.It was charac-terized by means of IR, EDS, the result reavals that the Ligand and central metal ions into the target compounds,and the crystal is tentatively identified as a new coordination polymer rystal. Use more than four generation of ammonium molybdate and organic sulfur acid and nickel-organic acid ligand system coordination compound as precursor, examines the stable state after mixed solution, organic acid ligand solution of Ni-Mo-S system has carried on the preliminary exploration, made clear sulfur-containing nickel molybdenum dipping solution, in order to obtain high efficiency diesel hydrodesulfurization catalyst laid a foundation.
