Q3 The dehydration of butanol is carried out over a silica-alumina catalyst at 680 K. CH3CH2CH2CH2OH + CH3CH = CHCH3 + H2O = cat The rate law is kPbu -rbu (1 + KBuPBu)2 With k = 0.054 mol/gcat*h*atm and KBu= 0.32 atm-?. Pure butanol enters a thin-tubed, packed-bed reactor at a molar flow rate of 50 kmol/hr and a pressure of 10 atm. a) What PBR catalyst weight is necessary to achieve 80% conversion in the absence of pressure drop? Plot and analyze X, p, f (i.e., (v/v.)) and reaction rate, -ra, as a function of catalyst weight. b) What fluidized CSTR catalyst weight is necessary to achieve 80% conversion? c) Repeat (a) when there is pressure drop, with the pressure-drop parameter a = 0.0006 kg?. Do you observe a maximum in the rate of reaction, and if so, why? What catalyst weight is necessary to achieve 70% conversion? Compare this weight with that for no pressure drop to achieve the same conversion
