The reaction by which such molecules are formed are:
Decompostion of Fe(CO)5 to form iron, which catalyzes Reaction 2
Fe(CO)5------->Fe + 5CO
Decompostion of CO to form CNT
6000CO------->C3000+3000CO2
Decompostion of CO to form armorphous carbon:
2CO------>C+CO2
In the process to be analyzed a frsh feed of CO saturated with Fe(CO)5 contains 19.2wt% of the latter component. the feed is joined by a recycle stream of pure CO and fed to the reactor where all of iron penta carbonyl decomposes. Based on laboratory data, 20% ofthe CO fed to the reactor is converted and the selectivity of CNT to amorphous carbon production is 9kmol CNT/kmol C. The reactor effluent passes through a complex separation process that yields three product streams: one consists of solid CNT, C, and Fe; a second is CO2 and the third is the recycled CO. You wish to determine the flow rate of the fresh feed (SCM/H) the total CO2 generated in the process (kg/h) and the ratio (kmol CO recycled/kmol CO in fresh feed).
A. Take a basis of 100 kmol fresh feed. Draw and filly label a process flow chart and do degree of separation process. Base the analyses for reactive systems on atomic balances.
B. Write and solve overall balances and then scale the process to calculate the flow rate (SCM/h) of fresh feed required to produce 1000kg CNT/h and the mass flow rate of CO2 that would be produced.
C. In your degree of freedom analysis of the reactor, you might have counted seprate balances for C (atomic carbon) and O ( atomic oxygen). In fact those two balances are not independent so one but not both of them should be counted. Revise your analysis if necessary and then calculate the ratio (kmol CO recycled/kmol CO in fresh feed).
D. Prove that atomic carbon and oxygen balances on the reactor are not independent equations.
