Conclusions 1.Heteropoly compounds of the type of mixed 12-series tungstosilicatea with the Keggin structure can be used as modifying additives in the composition of nickel-containing catalysts for the liquid-phase hydrogenation of coal, these additives increasing the yield of coal oils and the total yield of liquid products.2.These HPCs are structurizing promoters, and they also affect the dispersity of the metal entering into the catalyst composition, with a stabilizing effect on the nickel particles with sizes <30 å.3.This heteropolytungstate, in the process of thermolysis, does not decompose all the way up to 400‡C, and it does not completely lose its water.4.In a reducing medium at the reaction temperature, the mixed HPC changes over to the reduced form, but it does not decompose into simple oxides. |
