Precious metals. A chemical engineering reactor consists of a stainless steel chamber and associated pipe work weighing 3.5 metric tons, supported on a mild steel frame weighing 800 kg. The chamber contains 20 kg of loosely packed alumina spheres coated with 200 grams of palladium, the catalyst for the reaction. Compare the embodied energies of the components of the reactor, using data from the data sheets of Chapter 15 and from Table 6.2.
