Gas Flow in a Fluidized Bed Reactor

Catalytic butane dehydrogenation can be successfully carried out in a laboratory scale fluidized bed reactor operating at 310 °C and at atmospheric pressure. The catalytic particles have diameter 310 pm and density 2060 kg/m. Such a reactor is 150 mm in diameter and has a fixed 500 mm long catalytic bed. When the catalyst bed is fluidized with butane blown at a velocity of 0.1 m/s, it becomes 750 mm thick. 

To solve this example we use the same methodology as applied in the previous section we begin with the flow model selection and finish by identifying the parameters. 

With the computation of the algorithm identifying the parameters of the model we obtain  

Here Cqo = 0.79 kmol N2/kmol gas and Cq = 1 kmol N2/ kmol gas. Table 3.8 also contains the computed line that shows the dependence of the ln(l — C(0j)) vs 0 .
