abstract
In catalytic processes with catalyst deactivation, there is a big problem in estimating the remaining catalyst lifetime since industrial operating conditions are quite uncertain and consequently the non-uniform catalyst activity profile developed in the reactor during operation is unknown. In this article, a simple method for calculating the remaining catalyst lifetime from present operating data is reported. The spatial average catalyst activity, which indicates how much the catalyst has been deactivated, is proposed to denote the present catalyst activity in the reactor. For an isothermal plug flow reactor packed with non-porous catalyst, any catalyst activity profile determines the same reactant conversion if the spatial average activity related to this profile is the same. As a result, the average activity is easily calculated from present operating data without the information of the catalyst deactivation rate. The determined present average activity is used as an initial condition to estimate the remaining catalyst lifetime providing superbly accurate calculation results when the kinetic deactivation expression is characterized by the first order in the catalyst activity. The developed procedure is demonstrated using the water-gas shift reaction and methane steam reforming processes as examples.
