Ethanol, C2H5OH is produced by catalytic hydration of ethylene, C2H4. Some of the ethanol formed is converted in an undesired reaction to diethyl ether, (C2H5)20 and water. The feed to the reactor contains 53.7 mole% C2H4, 36.7% H2O and the balance is inert gas. In the reactor 5% of ethylene is converted and the yield of ethanol is 0.045. Take 200 mol feed gas as the basis of your calculation. a) Write the stoichiometric equations for the two reactions. (2 marks b) Determine the degree of freedom (DOF). c) Calculate the molar composition of the product gas leaving the reactor (2 marks) (8 marks) d) Discuss one factor that could increase the selectivity of ethanol production relative to diethyl ether production
