Question

Formaldehyde is produced by the catalytic oxidation of methanol using an excess of air according to the reaction:

CH3OH + (O) --> HCHO + H2O

 

Due to improper control the following side reaction also takes place.

HCHO + (O) --> HCOOH

 

In a typical run, the product gases from the reactor have the following composition by volume: methanol 8.6%, formaldehyde 3.1%, formic acid 0.6%, water vapor 3.7%, oxygen 16% and nitrogen 68%.

 

What is the percentage conversion of methanol to formaldehyde?

 

  1. 25%

     

  2. 30%

     

  3. 35%

     

  4. 40%
