This brief review of work from the author's laboratories summarises work on the steam reforming and CO2 reforming reactions, discussing some catalysts developed for these reactions. It then presents some work on the use of Mo and W carbides, with and without supports, for the CO2 reforming reaction, showing that zirconia-supported Mo2C has some potential for use in the reaction. Finally, the all-over CO2, balances of a number of reaction sequences for the utilisation Of CO2 are presented, these showing that the production of carbon by a sequence, involving CO2 reforming of methane followed by reduction of CO might be used to remove CO2 under certain circumstances; the C so produced could either be used as an energy carrier or disposed of.
