(30 points) The water-gas shift reaction is carried out isothermally in a flow reactor with no pressure
drop.
CO(g)+H2O(g)CO2(g)+H2(g)
Initial feed is composed of carbon monoxide, water, hydrogen, and argon (inert). The partial pressure
of initial feed is shown below.
PCO0=0.12atm,PH2O0=0.38atm,PH20=0.38atm,PN20=0.54atm
At the reaction temperature of 503K, determine the following.
(1)(7pts) Construct a stoichiometric table of water-gas shift reaction with the given information.
(2)(8 pts) The rate law of water-gas shift reaction can be expressed by the following Langmuir-
Hinshelwood kinetics.
-rCO=k(PCOPH2O-PCO2PH2Keq)(1+KCOPCO+KH2OPH2O+KCO2PCO2+KH2PH2)2
KCO=2.21atm-1,KH2O=0.0047atm-1,KCO2=0.4atm-1,KH2=0.052atm-1,Keq=38.8
Pre-exponential factor =0.92mol*g-1*s-1*atm-2, Activation energy =4.08kJmol
Calculate all parameters and express the rate law as a function of the conversion X.
(3)(8 pts) Calculate the equilibrium conversion xe and sketch the Levenspiel plot from x=0 to x=xe.
(4)(7 pts) Calculate the volume of an ideal CSTR operating at 503K, which achieves a conversion of
0.9xe.
