Procedure
A γ-alumina obtained as 1/16 inch extrudates from Criterion Catalyst Company L. P., Michigan City, Ind. was used. First, an ammonium heptamolybdate solution was prepared by dissolving (NH4)6Mo7O24 -4H2O in concentrated H3PO4 and water so that the ammonium molybdate concentration was 9.855 weight %, the H3PO4 concentration was 12.681 weight %, and water made up the rest. Then, 10 g of the alumina was impregnated at 25 ° C. with 5.32 g of the ammonium heptamolybdate solution to form a mixture. The mixture was then calcined in air at 538° C. for 6 hours to produce 10.18 g of a molybdenum oxide- and phosphorus oxide-impregnated alumina containing 2.807 weight % molybdenum and 2.096 weight % phosphorus (control catalyst).
