14C tracer studies using labeled ethanol indicate that the relative radioactivity/mole in hydrocarbon products is constant to carbon number 20. This result is consistent with (1) the two carbon units of ethanol remaining intact while on the catalyst surface and (2) that an adsorbed ethanol derived species serves to initiate chain growth but that it does not participate in chain propogation. The selectivity data obtained in a one atmosphere plug flow reactor are in excellent agreement with those obtained at seven atmospheres in a stirred tank reactor.
