ABSTRACT OF THE DISCLOSURE This invention relates to an extruded composition character- ized by its method of prepration. A finely divided refractory inor- ganic oxide, preferably as alpha-alumina monohydrate, is admixed with a peptizing agent and sufficient water to produce a mixture which has a weight loss on ignition at 900°C. of from about 50 to about 70%. The mixture is subjecting to shear-mixing, the intensity or severity of the shear-mixing being characterized by an energy input equivalent to from about 15 to about 120 watt-hours per pound of dry refractory in- organic oxide contained in said mixture over a period of from about 0.5 to about 5 minutes. The resulting dough is subsequently extruded and the extrudate calcined. The product is particularly useful as a hydrogentating catalyst in combination with a Group VIB and Group VIII metal component.
