Clean oxidation of alcohols in a trickle-bed reactor with liquid flow modulation

This work reports an experimental investigation of the catalytic oxidation of alcohols, using molecular oxygen as the oxidant and Pt/γ-Al 2O3 (1%w/w) as catalyst, in a trickle-bed reactor with ON-OFF liquid flow modulation under mild operating conditions. An aliphatic alcohol (ethanol) and an aromat...
