    Abstract

    An analysis of the carboxy reaction shows that the reaction rate is controlled by the chemical reactivity of the carbon and in-pore diffusion. An analysis of the airburn reaction shows that the rate at high temperatures is controlled by boundary layer diffusion and at low temperatures by boundary layer diffusion and in-pore diffusion. For the carboxy reaction the analysis enables benefits from optimising green mix formulation, final heat treatment temperature, etc., to be assessed. The airburn reaction is much less sensitive to carbon structure and reactivity. The analysis adapted to model the effect of cover is able to predict the reduction in the airburn rate with increasing depth of cover.
