Y. Lu et al., ACTIVATION OF CH4, CO2 AND THEIR REACTIONS OVER CO CATALYST STUDIED USING A PULSED-FLOW MICRO-REACTOR, Reaction kinetics and catalysis letters, 64(2), 1998, pp. 365-371
Pulse reaction showed that Co/Al2O3 catalyst was active for the high-t
emperature decomposition of CH4 and CO2. CH4 mainly was completely dec
omposed to give surface carbon, which could be inactivated quickly in
the absence of enough O-(ad) (arising from dissociation of CO2). CO2 w
as dissociatively adsorbed on Co-(0) sites to give CO(ad), and O-(ad),
which was a slow step. Further decomposition of CO(ad), happened in t
he case of CO2 decomposition.
