Abstract:
1. A stabilized composition for use in impregnating catalyst carriers comprising: (A) water; (B) catalytically active metals being in the form of and comprising: (1) at least one component providing at least one metal from Group VIB of the periodic table; and (2) at least one component providing at least one metal from Group VIII of the periodic table; wherein (i) said Group VIII metal is provided by a substantially water insoluble component; (ii) the molar ratio of said Group VIII metal to Group VIB metal is about 0.05 to about 0.45, provided that the amount of said Group VIII metal is sufficient to promote the catalytic effect of said Group VIB metal; (iii) the concentration of said Group VIB metal, expressed as the oxide, is at least about 3 to about 50 weight percent based on the weight of said composition; and (C) at least one substantially water-soluble, phosphorous-containing acidic component in an amount insufficient to solubilize said Group VIII metal at ambient temperature and sufficient to provide a phosphorous to Group VIB metal molar ratio of about 0.05 to less than about 0.25.
