Question
In a chemical process, the following reactions take place.
A---k1--->B---k2--->C
The reaction is carried out in a 500 L batch reactor. The initial concentration of A is 1.6 mol/L. While the formation of B is desired, the production of C is not desired. Calculated reaction rate constants at 100ºC:
k1: 0.4 hours-1
k2: 0.01 hour-1
a) If the reactions are irreversible, calculate the time change of substances A, B, C and draw their graphs.
b) When must the reaction be terminated in order to produce maximum B.
c) If the reaction is carried out in the CSTR and the retention time is 0.5 hours, at what temperature would you recommend the reaction be carried out for maximum B production? (E1=10.000 cal/mol, E2=20.000 cal/mol)
