Temperature neohexane reactions

Fig. 16. Selectivity in the formation of various adsorbed 3C and 2C complexes upon reactions of neohexane with hydrogen for Pt/Si02, Pt-Ag/Si02, and Pt-Au/Si02 with compositions and temperatures of reactions as indicated (H-hydrogenolysis).

Fig. 14. Product patterns as a function of temperature in neohexane/H2 reactions (a) Pure Ni measured at low temperatures (b) pure Ni diluted by Si02 and self-poisoned by the running reactions (notice that methane > neopentane, i.e., multiple reactions are also running at the lowest conversions) (c) alloy of Ni/Cu in the ratio 65 35 (increase in methane < decrease in neopentane this indicates that molecules other than methane are formed, i.e., the role of ay is larger here).

Fig. 15. Selectivity for nondestructive reactions in hexane (HEX) and neohexane (NEOHex) reactions (in H2) in the temperature range 173-603 K. From V. Ponec et ai, Faraday Discuss. No. 72, p. 33.
