Hydrous metal oxide ion exchangers for preparation of catalysts for direct coal liquefaction
A group of hydrous oxide ion-exchange compounds which can be used to prepare hydrogenation catalysts by a novel synthesis route has been identified. These materials offer several advantages including high surface area, dispersion of any metal or mixture of metals and promoters over a wide concentration range, and adjustment of substrate acidity as well as active metal oxidation state. Catalysts prepared by exchanging the Na ion of sodium hydrous titanate for Ni, Mo and Pd were tested for use in direct coal liquefaction. Results of hydrogenation experiments performed with the addition of the catalysts to a slurry of a bituminous coal in a coal derived solvent demonstrated that hydrous titanate catalysts with active metal loadings as low as 1% were equally effective for liquefying coal as a commercial Ni-Mo/Al/sub 2/O/sub 3/ catalyst containing 15% wt active metals.
