Reaction kinetic studies in a mixed flow reactor
1. A liquid phase reaction is to be carried out in a suitable reactor. The stoichiometry of the reaction is A-> R. The feed concentration is 0.90 mol A/liter and is available at a rate of 100mol A/min. The following reactors may be considered for choice.
- Mixed flow reactor
- Tubular flow reactor
- Recycle reactor with a recycle ratio of 0.50.
It is desirable to achieve a fractional conversion of 0.778. Which one of the above mentioned reactors do you recommend and why? The following data, available for the reaction, may be used in your calculations.
| Rate, mol A/lit. min. | 0.1 | 0.3 | 0.5 | 0.6 | 0.5 | 0.25 | 0.1 | 0.06 | 0.05 |
| Concentration, mol A/lit. | 0.1 | 0.2 | 0.3 | 0.4 | 0.5 | 0.6 | 0.7 | 0.8 | 1.0 |
2. The liquid phase reaction A -> R + S follows first - order kinetics with a reaction velocity constant of 0.80 k sec-1. A feed having a concentration of 1 k mol A/m3 at a rate of 1.60 m3/k sec. is available for processing. A cascade having three equal sized back mix reactors, with each vessel having a hold - up volume of 50 liters, is available for service. When this reaction is carried out in the cascade, find the final conversion which can be achieved.
