The complex reactions involved in the oxidation of formaldehyde to formic acid over a Vanadium titanium oxide

Question:

The complex reactions involved in the oxidation of formaldehyde to formic acid over a Vanadium titanium oxide catalyst are shown below. Each reaction follows an elementary rate law.HCHO+12O2k1HCOOHk1CO+H2O2HCHOk2HCOOH3H2O+HCOOCH3k3CH3OH+HCOOH

Sketch the trends or results you expect before working out the details of the problem.
Let A = HCHO, B = O2, C = HCOOH, D = HCOOCH3, E = CO, W = H2O, and G = CH3OH. The entering flow rates are FA0 = 10 mol/s and FB0 = 5 mol/s, and υ0 = 100 dm3/s. At a total entering concentration CT0 = 0.147 mol/dm3, the suggested reactor volume is 1000 dm3.
Additional information:
At 300 K
k1=0.014(dm3mol)1/2/s,k=0.007dm3mol⋅sk3=0.014/s,k4=0.45dm3mol⋅s

a. Plot the molar flow rates of each species along the volume (length) of the reactor on the same figure and then analyze why the profiles look the way they do.
b. Plot and analyze Y˜C,S˜A/E,S˜C/D,and S˜D/G along the length of the reactor. Note and explain any maximums and the volume at which they occur.
c. Plot and analyze the overall HCOOH yield and overall selectivity of HCOH to CO, of HCOOCH3 to CH3OH, and of HCOOH to HCOOCH3 as a function of the ΘO2.
Suggest some conditions to best produce formic acid. Write a paragraph describing what you find.
d. Compare your plot in part (a) with a similar plot when pressure drop is taken into account with α = 0.002 dm–3. Note any unusual differences between parts (a) and (d).
e. Suppose that E1 = 10000 cal/mol, E2 = 30000 cal/mol, E3 = 20000 cal/mol, and E4 = 10000 cal/mol, what temperature would you recommend for a 1000-dmPFR?
