It is desired to design and build a reactor that produces 1200 mol acetaldehyde (CH:CHO) per hour using pure ethanol (C2H5OH) and air (79 mol % N2, 21 mol% 02) as reactants. Two reactions (R1 and R2) as shown below are taken place in the reactor: R1 produces a desired product while R2 produces an acetic acid (CH3COOH) by-product. C2H5OH (g) + 1/2O2 (g) CH:CHO (g) + H20 (g) 2CH3CHO (g) + O2(g) 2CH3COOH (g) (R1) (R2) Laboratory data indicate that if new catalyst is used, the feed ratio (mol ethanol per mol oxygen) is corresponding to 4.92. The reactor is operated isothermally at 300 C and 1 atm, while ethanol is expected to achieve 25% of conversion and the selectivity is 0.6. Laboratory data indicate that if new catalyst is used, the feed ratio (mol ethanol per mol oxygen) is corresponding to 4.92. The reactor is operated isothermally at 300 C and 1 atm, while ethanol is expected to achieve 25 % of conversion and the selectivity is 0.6. a) Determine the molar flow rate (mol/h) of all components at inlet and outlet stream of the reactor. b) Using the heat of reaction method, calculate the required heat (kW) to be added or removed in order to maintain the reactor temperature at 300 C. c) If air is replaced by pure oxygen, would the heat calculated in part (b) be higher, lower, or the same? Justify your answer. Additional information: Cp, CH3CHO (8) = 54.7 J/mol C; Cp, CH3COOH (g) = 66.5 J/mol C ACH3CHO(g) = -166.2 kJ/mol, A CH3COOH () = -432.8 kJ/mol =
