1. Objective

A catalytic reactor is to be designed for the dehydrogenation of ethanol. The specifications specify that 20 t per hour of a water-ethanol mixture with 95% ethanol by mass should be processed.

Franckearts and Froment [1] studied the catalytic dehydrogenation reaction of ethanol and found, for a temperature below 300 ˚C and for a copper oxide catalyst containing 5% cobalt oxide and 1% chromium oxide, that it obeyed only the following stoichiometric scheme: $\begin{array}{l} {CH}_{3} {CH}_{2} OH ⇄ {CH}_{3} CHO + H_{2} \\ (A) (R) (S) \end{array}$
