The equations relating the adsorption equilibrium constant and reactionrate constants on a single catalyst pellet to measureable properties of pulse-response experiments were derived by means of statistical moment theory. Under atmospheric pressure and at a temperature upto 340℃ the effective diffusivities and the adsorption equilibrium constants oi carbon monoxide and the rate constants for shift reaction CO + H2O = CO2 + H2 on a B110 catalyst pellet were measured by using ordinary thermal conductivity cell(TCC). It has been proved to be a new and valuable technique for determining the kinetic parameters of gas-solid heterogeneous catalytic reaction.
