With an increase of the palladium content of the catalyst from 0.2 to 0.5 and 1.0 wt.%, the yields during toluene conversion at 400 ◦C do not change significantly. Therefore, the formation of methane is attributed to Haag¨CDessau cracking, rather than to hydrogenolysis on the noble metal . It is only upon reducing the Pd content to as little as 100 wt. ppm that the catalytic behavior changes in a pronounced manner; the conversion of toluene drops from 100 to 38.2% at 400 ◦C, and other aromatics become the dominant products, in much the same way as if aromatics had been converted on metal-free, acidic zeolites . |
