Abstract:
1. A method for operating a catalytic reforming assembly, said method comprising: injecting a quantity of oxidizer gas and a quantity of combustion gas into a reformer to form a mixture; channeling the mixture across a catalyst bed to form a reformate gas stream; measuring a temperature at a plurality of points throughout the catalyst bed using a plurality of temperature sensors; measuring a level of the oxidizer gas in the reformate stream using a plurality of oxidizer gas sensors positioned at a plurality of exit-plane locations across an exit plane of the catalyst bed; and determining a health of the catalyst bed at each of a plurality of bed locations of the catalyst bed based on a measured temperature at a corresponding point of the plurality of points and a measured level of the oxidizer gas at a corresponding downstream location of the plurality of exit-plane locations; and adjusting a quantity of oxidizer gas injected at each of the plurality of bed locations based on the determined health of those locations.
