Carbon filament formation on a nickel catalyst during steam reforming of hexane in an integral reactor could not be ascribed to cracking of methane, nor to disproportionation of carbon monoxide since these reactions were not thermodynamically favorable at any point in the reactor. Comparison of reactor conditions with microbalance studies of carbon formation from hexane and ethylene also indicated that carbon did not result from reaction, individually, of these components of the reaction gas stream. Carbon formation, therefore, must have resulted from an interaction of the hexane feed, and the products of secondary cracking reactions, or from unstable intermediates in the cracking process.
