Mechanistic considerations show that pressure must be taken into account in evaluating oxidative coupling catalyst performance, and predict an upper limit of around 30% yield of higher hydrocarbons at one atmosphere.

- Lunsford has noted that the C-H bond in ethylene isstronger than that in methane, and suggested that a catalyst might be found for which the former is less reactive and hence the constraints discussed here need not apply J.H. Lunsford, in:Methane Conversion, eds. D.M. Bibby, C.D. Chang, R.F. Howe and S. Yurchak (Elsevier, New York, 1988) 359.). However, since ethylene is more reactive even for gas-phase reactions with OH and related species, in spite of its stronger bond, it does not seem very likely that this could be achieved.
