Abstract: The TAP transient pulse response experiment has been used for heterogeneous catalytic reaction studies. Interpretation of TAP response data by moment analysis requires analytical moment expression of the gas exit flow rate. The zeoth moment expression of the exit flow rate of a reactant gas from the TAP reactor packed with bimodal-pore-structure catalyst for irreversible reaction case is proposed. The obtained expression was found to be similar to that for non-porous catalyst except that the rate constant is multiplied by an overall effectiveness factor. The overall effectiveness factor is the product of the effectiveness factors in the two porous regions in the catalyst pellet. Both effectiveness factors as well as the overall effectiveness factor are defined similarly to those in steady-state conditions.
