A homogeneous, amorphous catalyst support comprising a modifying-metal-oxide and a base-metal oxide, the catalyst support having a Surface to Bulk modifying-metal /base-metal atomic ratio of from about 0.6 to about 1.3 and exhibiting an X-ray diffraction having broader line width and lower intensit y than is exhibited by the base-metal oxide is disclosed. More specifically, a homogeneous, amorphous silica-modified-alumina catalyst support useful in th e Fischer-Tropsch process is disclosed. A silica-modified-alumina catalyst support of the present invention maintains the desirable properties of alumi na and exhibits higher resistance to acid than unmodified alumina.
