Effect of Varying Conversion

Of the reactions of the various types of alkane with hydrogen, those of the n-alkanes, especially n-hexane have been the focus of attention because of their 

We turn now to the metals that are more active than palladium and platinum for the reactions of alkanes with hydrogen. Rhodium catalysts have been the subject of a number of investigations they were active for n-hexane hydrogenolysis between about 420 and 500 K, and were characterised by giving

TABLE 14.3. Product Selectivities for the Reaction of n-Hexane with Hydrogen over Rhodium Catalysts at 498 K.  

Ru/ZSM-5 catalysts modified by inclusion of either rhenium or rhodium or nickel have been examined for -hexane hydrogenolysis at 403 and 433 K methane was the main product in most cases, but Ru-Ni/ZSM-5 gave chiefly isoheptane from the reaction of n-heptane at 423 K.
