1. Figure 1 below outlines the basic catalytic design of four different fixed bed reactors denoted a to d. Using your knowledge and understanding of catalytic reactor design, outline the general characteristics of each of these reactors and the typical reactions that you might expect to occur within them. Base your answers in relation to heat transfer and pressure drop considerations. Figure 1: Four fixed bed catalytic reactors. [8 marks] [Total 8 marks] 2.
