Catalytic wet oxidation of ethanol in an integral trickle-bed reactor operated with liquid flow modulation

The effect of liquid flow modulation on the performance of an integral trickle-bed reactor used for carrying out the catalytic wet oxidation of ethanol is analyzed. Particular emphasis is devoted to examine whether the induced periodic variations in conversion are affected by prolonged operation. A...

Liquid flow is open/closed periodically by means of a programmable logic controller with given splits and at different total cycle period.

In addition, the average conversion obtained with periodic operation is compared to that of the steady state at different cycle periods.
