Abstract
A method and system for determining changes in the catalytic activity of reforming catalyst where an outlet temperature of the catalytic reactor is measured and a temperature approach to equilibrium calculated based on the measured outlet temperature. The temperature approach to equilibrium is compared to an empirical model-based temperature approach to equilibrium calculated for the same operating conditions, the comparison showing changes in the catalytic activity of the reforming catalyst.
