Catalyst and support, their methods of preparation, and processes employing same
A catalyst support is prepared from a composite comprising two or more inorganic oxides by forming the composite into a shaped support material having at least 0.8 cc/gm of its pore volume in pore diameters of 0 nm (0A) to 120 nm (1,200 A) and at least 0.1 cc/gm of its pore volume in pore diameters of 120 nm (1,200 A) to 5,000 nm (50,000 A) and heating said shaped support material in the presence of steam at sufficient elevated temperature, steam pressure, and time period to increase the average pore diameter of said shaped support in the absence of any appreciable reduction in pore volume. The inorganic oxide composite is selected from the group consisting of a mixture of alumina and silica; a mixture of alumina, silica, and oxides of phosphorus; a mixture of alumina and oxides of phosphorus; a mixture of alumina and boria; a mixture of alumina, boria and oxides of phosphorus; and a mixture of alumina, magnesia, and oxides of phosphorus, the oxides of phosphorus being calculated as P/sub 2/O/sub 5/ and the quantities being based upon the weight of the composite. A catalyst is prepared by impregnating the steam-treated support with at least one hydrogenating metal. The catalyst can be used suitably in hydrocarbon conversion processes, such as a process for the hydrodemetallization of a hydrocarbon stream containing asphaltenes and a substantial amount of metals.
