Analytical expressions are developed for the time‐dependent reactant concentration and catalyst activity in an isothermal CSTR with Langmuir‐Hinshelwood kinetics of deactivation and reaction. Several parallel and series posioning mechanisms are considered for a reactor which, without poisoning, would operate at a unique steady state. The use of matched asymptotic expansions and abandonment of the usual initial‐steady‐state assumption give results, valid from startup to final loss of activity, whose accuracy can be improved systematically.
