Continuous Multiphase Reactors

Figure 21-8 shows a continuous reactor used for bubbling gaseous reactants through a liquid catalyst. This reactor allows close temperature control. The fixed bed (packed bed) reactor is a tubular reactor that is packed with solid catalyst particles. The catalyst may be placed in one or more fixed beds (i.e. layers across the reactor) or it may be distributed in a series of parallel long tubes. The latter type of fixed bed reactor is widely used in industry (e.g., in ammonia synthesis) and offers several advantages over other forms of fixed beds. The type of reactor shown in Figure 21-9 is used in a heterogeneous reaction system involving catalyzed gas reactions. The fixed bed reactor gives fewer chances for backmixing, ...
