Vanadium-catalysed gasification of carbon and its application in the carbothermic reduction of barite

Sodium vanadate, a waste from Bayerʹs alumina process was used as a catalyst in the CO2 gasification of active charcoal. The catalytic effect was quite evident with the observed enhanced rate of gasification accompanied by the typical compensation effect. This effect has been able to predict the observed anamolous behaviour of the vanadium catalysed carbothermic reduction of barite.
