Question

Ps-26 Ethyl acetate is an extensively used solvent and can be formed by the va vapor phase esterification of acetie acid and ethanol. CH,-C-00H + CH,CH,0H- CH,-C-oCH,CH, + H,Q The reaction was studied using a micro-porous resin as a catalyst in a packed bed micro reactor [Ind. Eng. Chem. Res., 2612). 198(1987)1. The reaction is first-order in ethanol and pseudo-zero-order in acetic acid. The total volumet- ric feed rate is 25 dm/min, the initial pressure is 10 atm, the temperature is 223'C, and the pressure drop parameter, a, equals 0.01 kg. For an equal molar feed rate of acetic acid and ethanol, the specific reaction rate is about 1.3 dm/kg cat -min. (a) Calculate the maximum weight of catalyst that one could use and main- tain an exit pressure above 1 atm. IAns.: W 99 kgl (b) Write out the CRE algorithm and then solve these equations analytically to determine the catalyst weight necessary to achieve 90% conversion. (c) Write a Polymath program to plot and analyze X, y, and fuvo as a function of catalyst weight down the packed-bed reactor. You can either use your analytical equations for x, y and for you can plot these quanti ties using the Polymath program.

Mainly need part C, not sure what it is asking.
