A combination of experiments using TAP, and isotopic labelling of hydrocarbons using 11C over metal catalysts has provided useful information about the formation of carbon surface species and their activity. The formation of non-reactive surface species following high temperature CO or CH4 adsorption was shown to be more likely at high temperatures, and that this was a fairly rapid process. The activation energy for C-C coupling reactions was found to be higher following promotion of a Ru catalyst with V. Differences in n-/iso- ratio between labelled and non-labelled products indicated that different reaction pathways led to the formation of n-hexane and iso-hexane.
