thermodynamics
There are three types of conditions used for methanol manufacture: • high pressure: 250-300 atm; 300-450 o C using ZnO-Cr2O3 catalysts • medium pressure: 150 atm; 300 o C using ZnO-CuO catalysts • low pressure: 50 atm; 225 o C using Cu-ZnO-Al2O3 catalysts. Assume your industrial reactor has a feed of synthesis gas in the stoichiometric ratio 1 CO : 2 H2. Using your answers to (b), give your reasoning as to which of the three types of conditions you would recommend for operations. You must show all your calculations used to justify your decision. [HINT: Assume the gases obey Raoult’s law and that fugacity coefficients can be neglected. You may it useful to use an online cubic equation solver, such as https://keisan.casio.com/exec/system/1181809414 (accesse
