Q1: The dehydration of butanol is carried out over a silica-alumina catalyst at 680 K. CH,CH,CH,CH,OH>CH,CH=CHCH,+H,0 cat The rate law is kP. Bu (1+K„P.) Bu Bu = 0.32 atm-1. Pure butanol enters a thin-tubed, with k = 0.054 mol/gcat.h.atm and KBu packed-bed reactor at a molar flow rate of 50 kmol/hr and a pressure of 8 atm.

Question
Q1: The dehydration of butanol is carried out over a silica-alumina catalyst at 680 K. CH,CH,CH,CH,OH- →CH,CH=CHCH, +H,O cat The rate law is kP. Bu Bu (1+K, Bu Bu 0.32 atm-1. Pure butanol enters a thin-tubed, with k = 0.054 mol/gcat.h.atm and KBu packed-bed reactor at a molar flow rate of 50 kmol/hr and a pressure of 8 atm. a) What PBR catalyst weight is necessary to achieve 90% conversion in the absence of pressure drop? Plot and analyze X, and reaction rate, as a function of catalyst weight. b) What fluidized bed reactor catalyst weight is necessary to achieve 90% conversion? %3D c) Repeat (a) when there is a pressure drop, with the pressure-drop parameter a = 0.00085 kg-1. Compare this weight with that for no pressure drop to achieve the same conversion and give your comment.
