The rates of the alkali catalysed water-gas shift reaction (WCS) and steam gasification of carbon have been studied at 1.5 x 10' Pa total pressure as a function of temperature (8OGlOOOK), feed composition (pure H,O or mixtures of H,O with either CO1, H, or CO), alkali metal (Na, K, Rb, Cs) and K,C03

In this study reaction rate data are presented of potassium carbonate-catalysed CO, gasification of an activated carbon, measured in a Packed Bed Balance Reactor over a CO2 pressure range of 0.05-2.03 MPa at 1050 K. As a result of CO inhibition the reactor only behaves differentially at CO, conversi
A significant fraction of the potassium catalyst can be lost by vaporization during catalysed carbon gasification. The extent of this loss depends primarily on the reaction start-up procedure. Temperature programmed experiments show that, under inert atmospheres, both KOH and K,CO, react with carbon
The literature on the potassium catalysed gasification of carbon in CO2 is critically reviewed with respect to the mechanism and the experimental 'facts' relevant to the mechanistic considerations. It is concluded that bulk intercalation compounds (CsK, r&K, etc.) are not present under gasification
