An Inherited Rate Law

Re-estimating a Catalytic Oxidiser's Commissioning Kinetics from a Shutdown Light-off Excursion

A chemical engineering paper from the School of Settled Matters and the School of Continuous Improvement asks whether the kinetic constants fitted at a catalytic oxidiser's commissioning, and kept in its control model through a monolith-layer replacement and four years of service, still describe the platinum-on-alumina bed it now holds. Four years of operating records cannot tell, because the bed is mass-transfer controlled at operating temperature; a light-off excursion during one shutdown finds the apparent activation energy unchanged but the reaction rate group at 230 °C fallen to 0.41 of its commissioning value, moving the half-conversion temperature from 196 to 218 °C.
