摘要：
The surface conditions of an industrial iron catalyst were monitoredin situ by work function measurements and measurements of thermal desorption of potassium ions. Changes in activation energy for potassium ion desorption and in work function values during catalyst activation and deactivation are discussed in terms of the potassium coverage and chemical composition of the catalyst surface.
