Question 4 The acetic acid synthesis reaction between ethanol (CH3CH2OH) and oxygen (02), CH3CH2OH + O2 + CH3COOH + H2O can occur isothermally in gas-phase following the elementary rate law by using a solid catalyst at 300 o C and 1 atm. Solve the following cases related to this reaction a) Describe effect of the solid catalyst to the kinetics of the above reaction. b) At 200 o C the rate constant, k = 0.04 dm3 mol-1 min-1. What is the rate constant at 300 o C if the activation energy of the above catalytic reaction is 24 kJ mol-1? c) An initial test using a packed-bed reactor (PBR) that has 15-cm internal diameter and 7- meter length shows that the pressure drops to 0.5 atm. Determine the pressure drop parameter, D if the bulk density the solid catalyst is 2000 kg m-3. d) By using answers from (b) and (c) estimate the conversion of methanol in the PBR with 1- km length and the same internal diameter if the feed, which contains the molar ratio of CH3CH2OH:02 = 1:2 enters the reactor at 10 L min-1. e) The flow of reacting gas in (d) is turbulent. What will happen to the conversion of methanol if the particle size of solid catalyst is 80 % of original size? Assume the flow is still turbulent and the change of other parameters in the Ergun equation is negligible including the bulk density of the catalyst
