A novel membrane reactor with two zones containing structured filamentous catalytic beds was proposed for propane nonoxidative dehydrogenation. Catalytic filaments with a similar to7 similar to mum diameter consist of silica cove-red by porous alumina with 0.5% Pt/1% Sn. These filaments were placed in parallel in a tubular membrane reactor. The hydrodynamic characteristics of the reactor correspond to the properties of a multichannelled microreactor with laminar flow, a low pressure drop, and a narrow residence time distribution. A propane conversion of 0.34 at 823 K was reached, instead of the 0.24 equilibrium value. The catalyst demonstrated a suitable stability under periodic regeneration in oxidative atmosphere.
