Abstract

We have previously demonstrated that fullerene soots catalyze hydrogen-transfer reactions that are useful for hydrocarbon processing, including conversion of methane into higher hydrocarbons. In this paper we describe the effect of doping fullerene soot with alkali and transition metals for converting methane and other light hydrocarbons. The fullerene soot was found to lower the temperature threshold for methane activation compared to other carbons; however, the selectivity to C2 hydrocarbons was quite low (20%). In contrast, when the soot was doped with metals such as Mn or K, the overall yield of hydrocarbons increased and selectivities as high as 80% were achieved. When potassium was used as a dopant, the selectivity to C3 and C4 hydrocarbons also increased.
