The dehydrogenation of ethanol to form acetaldehyde is carried out in a flow reactor.
C2H50H (g) -) CH3CH0 (g) + H2 (g)
A It!!! molih of ghanol at 4!!!!‘1! is fed to me reactor. The gg average heat capacities of
QZHEOH CH3€HO and H2 are 73, 96, 29 {meol K}, resfltivelx.
a) Address the effect of vying the reaction m (flour 0% to 99%} on the exit stream
temperature (“Ci for an adiabatic reactor. Use a conversion increment of 3%, and show all
details. Plot temperature versus conversion
b) Calculate the heat flow in or out of the reactor, if the reactor is operating isothermall}.r at
400 °C. Address the effect of conversion on the heat flow rate (use10% to 100%, with
increment of 2%}. Plot heat flow rate versus conversion.
e] Do you prefer to run the reactor isothermal];r or adiabatically? Why? (1) Assume that the reaction occurs in an isothermal plug flow reactor. Calculate the reactor
volume {in ms) as a function of conversion, using the formula below for conversions 10%
to 99%, increment of 3%: Vans _ Fczflsoflp j 1 d3 Commas o hue-Em" (1—1) Where it is the conversion Fernsonfl = ticzflsoap Inlet molar flow rate- Check the units!
E = 16.?11 kJimol k, =4.014 x 10'3 (s'l) R: 3.3141im01K cmmmflsm msi'mol Then determine hydrogen permeation flux (molfmzsll through Pd membrane using: Sieverts’ Law: Jm = %(Pfl§ _P§P) where Q”? = (Joe-EV”

P.“ = 1200 kPa Pm, = 100 kPa A5 347 cm2 Plot Sieverts’ Law, and molar hydrogen permeated versus conversion. Comment on results. e) Repeat part (d) but using an adiabatic Continuous Stirred Tank Reactor (CSTR) which
volume can be calculated using: Fcznsoap x .
