Abstract: AN IMPROVED METALLIC CATALYST OF HIGH SURFACE AREA A PREPARED FROM AN ALLOY COMPRISING ALUMINUM AND A SECOND METAL WHICH IS SOLUBLE IN OXIDIZING ACIDS. THIS ALLOY IS CONTACTED WITH AN OXIDIZING ACID FOR A TIME PERIOD AND AT A TEMPERATURE AND ACID CONCENTRATION SUFFICIENT TO DISSOLVE A PORTION OF THE SECOND METAL. THE ALLOY IS SUBSEQUENTLY CONTACTED WITH AN ALKALI METAL HYDROXIDE UNDER CONDITIONS SUFFICIENT TO CONVERT THE ALUMINUM AT THE SURFACE OF THE ALLOY TI O ALUMINUM HYDROXIDE. THE ALLOY THUS TREATED IS THEN HEATED IN THE PRESENCE OF OXYGEN FOR A TIME PERIOD AND AT A TEMPERATURE SUFFICIENT TO CONVERT THE ALUMINUM HYDROXIDE TO ALUMINUM OXIDE.

Abstract: A Group VIII metal-tin catalyst is described in which the molar ratio of Group VIII metal to tin is about 1.7 to 15. The catalyst is prepared by heating reducible compounds of a Group VIII metal and tin in oxygen and then reducing the resulting product with hydrogen. A metallic nickel-tin composition is an example of this catalyst.

Abstract: A GERMANIUM COMPONENT IS UNIFORMLY DISPERSED THROUGHOUT A POROUS, HIGH SURFACE AREA CARRIER MATERIAL BY THE STEPS OF: FIRST, REDUCING GERMANIUM DIOXIDE WITH HYDROGEN; SECOND, DISSOLVING THE RESULTING REDUCED MATERIAL IN AN AQUEOUS SOLUTIONOF CHLORINE TO FORM A SOLUTION THEREOF; THIRD, IMPREGNATING A HIGH SURFACE AREA, POROUS CARRIER MATERIAL WITH THE RESULTING SOLTUION; AND, FINALLY DRYING AND CALCINING THE RESULTING IMPREGGNATED CARRIER MATERIAL. KEY FEATURE OF THIS METHOD OF PREPARATION INVOLVES THE USE OF THIS SOLUTION OF THE REDUCED GERMANIUM COMPOUND IN CHLORINE WATER TO IMPREGNATE THE CARRIER MATERIAL, THEREBY ACHIEVING UNIFORM DISPERSION OF THE GERMANIUM COMPONENT IN THE CARRIER MATERIAL.
