Problem (6) P10-11, Methyl ethyl ketone (MEK) is an important industrial solvent that can be pro- duced from the dehydrogenation of butan-2-ol (Bu) over a zinc oxide catalyst Ind. Eng. Chem. Res., 27, 2050 (1988)]: Bu MEK + H2 catalyst The following data giving the reaction rate for MEK were obtained in a dif- ferential reactor at 490C. PB. (atm) PMEK (atm) 2 5 0 0.1 0 0 0.5 2 1 1 1 1 2 0 0 PH, (atm) 1 0 10 0.05 9 MEK (mol/h.g cat.) 0.044 0.040 0.069 0.060 0.043 (a) Suggest a rate law consistent with the experimental data. (b) Suggest a reaction mechanism and rate-limiting step consistent with the rate law. (Hint: Some species might be weakly adsorbed.] (C) Apply one or more of the six ideas in Table P-3, page xviii to this problem. (d) Plot conversion (up to 90%) and reaction rate as a function of catalyst weight for an entering molar flow rate of pure butan-2-ol of 10 mol/min at an entering pressure P. = 15 atm. Wmat = 30 kg. (e) Write a question that requires critical thinking and then explain why your question requires critical thinking. (Hint: See Preface Section B.2.) (1) Repeat part (d), accounting for pressure drop and a = 0.03 kg-Plot y and X as a function of catalyst weight down the reactor up to 25 kg
