Question

3. (35 points) Ethanol has recently been produced by the following ele reaction, mentary gas- CH4 CO2 CH COOH + 4H2 using a copper-carbon catalyst in a packed bed reactor at 500K. The reactants are at 400 kPa in stoichiometric amounts and the initial volumetric flow rate is The m/mol.kg.hr rop parameter, a, is 0.001 kg and the rate constant, k, is 0.00S State the type of reactor Phase of reaction medium Write down the rate law If a 70% conversion is expected in this reactor, what amount of catalyst, w, is needed and what will be the final pressure, P, in the reactor? Develop the two coupled differential equations you will solve to obtain W and y P/Po in terns of conversion. Evaluate all constants in the equation and write a.

Explanation / Answer

Type of reactor : Packed Bed Reactor

Phase of reaction medium: Gas phase

Rate law of the reaction may be estimated by finding the order n of the reaction
