Pure ethanol vapor is fed to a reactor packed with alumina catalyst, at the rate of 100 kmole / hr. The reactor products comprise: ethylene: 95 kmole / hr, water vapour: 97.5 k mole / hr and diethyl ether: 2.5 kmole/hr. The reactions occuring can be represented by: C2H5OH → C2H4 + H2O 2C2H5OH → C2H5 - O - C2H5 + H2O The percent conversion of ethanol in the reactor is________________?
Correct answer: A. 100
- A. 100
- B. 97.5
- C. 95
- D. 2.5
Explanation
Formation of 95 kmol/h ethylene consumes 95 kmol/h ethanol, while 2.5 kmol/h diethyl ether consumes 5 kmol/h ethanol. Total ethanol consumed is therefore 100 kmol/h out of 100 kmol/h fed, giving 100% conversion.
