Procedure

The zeolites were prepared as described in Example 2. The precious metal was added as follows. Sodium ZSM-5 (Si/Al=14) was slurried in about 0.01M solutions of the precious metal compounds of platinum, palladium and ruthenium proportioned to achieve 1% loadings. The compounds utilized for these exchanges were tetraamineplatinium nitrate, palladium(II) acetate and ruthenium(III) chloride. The rhodium loaded ZSM-5 was prepared by slurrying in an approximately 0.033M solution proportioned to give a 4% weight loading of rhodium(III) nitrate. Each was stirred at least 18 hours then filtered and calcined at 450° C. for 3 hours.
