Fluidized bed tests with silver catalysts used in the oxidation of ethylene to ethylene oxide showed fluidization instabilities due to catalyst agglomeration. One method of avoiding the agglomeration problem, yet utilizing the excellent heat transfer property of a fluidized bed, is by the immersion of fixed catalyst coated strips in an inert fluidized bed. Small scale tests with this method, have shown that excellent temperature control can be achieved without serious adverse effects on catalyst performance. Kinetic data are presented for a limited range of flow conditions, and are correlated by an empirical rate equation of the form
