Abstract

A control system for a catalytic process include: a) an electroconductive support having a layer of a catalyst thereon; b) a device for applying DC current of one polarity to the catalytic layer and the opposite polarity to the electroconductive support; c) a device for controlling DC current; d) a device for measuring the polarization impedance across the catalyst layer and the electroconductive support; e) a device for comparing the measured polarization impedance with a reference value; and f) a device for varying the DC current to the catalyst layer and the electroconductive support when the measured polarization impedance differs from the reference value. The control system may further optionally include: g) a device for heating the electroconductive support; h) a device for controlling and varying the application of heat; and i) a device for varying the application of heat to the catalyst and the electroconductive support when the measured polarization impedance differs from the reference value. Also disclosed is a process wherein the catalyst is contacted with a stream of light hydrocarbon fuel or combustion exhaust.
