Procedure
The catalyst of this example was prepared in a similar manner as described in Example 5. In this case, an ammoniumheptamolybdate solution was prepared by dissolving 4.63 g of ammoniumheptamolybdate in 20 mL of water and adjusting the volume to 25 mL to provide a solution with a molybdenum concentration of 0.15 mol/L. Then, 11.03 mL of the above impregnating solution was used to impregnate 10 g of the zeolite support. The impregnated support was then placed in an oven and dried with air (1 L/min) by heating to 70° C. at a rate of 1° C. per minute and holding for 10 hours. Then, the temperature was increased to 120° C. at a rate of 1° C. per minute and held for another 10 hours. Finally, the temperature was increased to 500° C. at a rate of 1° C. per minute and held for 5 hours. The finished catalyst sample was sieved to remove fines and to obtain the desired 315-500 microns fraction and then tested as described above. The catalyst was found to have a molybdenum content of 10.0% wt.
