Abstract
A catalytic composite of from about 4 to about 30 wt. % Group VIB metal, from about 1 to about 10 wt. % Group VIII metal and a refractory inorganic oxide carrier material is manufactured by co-extruding a Group VIB metal compound, a Group VIII metal compound and a refractory inorganic oxide, the resulting extrudate being subsequently impregnated with a Group VIB metal compound and a Group VIII metal compound to yield an improved catalyst.
