Abstract

A kinetic study is made of the reaction of activated carbon gasification by CO2 catalysed by MoO3 and K2CO3, using a microbalance to record the loss of weight as a function of time. Orders and activation energies were measured. MoO3 is found to be a good catalyst at low temperatures and moderate pressures. The effect of loading on reactivity shows saturation above ≈ 0.3 wt %. The catalytic effect of the mixture MoO3/K2CO3 is found to be slightly above the effect expected by the addition of the separate effects of the two catalysts. A brief reference is made to the possible mechanism for these reactions.
