NITROBENZENE LIQUID-PHASE HYDROGENATION IN A MEMBRANE REACTOR

This work presents the potentialities of a catalytic membrane reactor in a gas-liquid-solid reaction. A catalytic membrane has been prepared via well-controlled platinum deposition within the porous framework of a gamma-Al2O3 mesoporous membrane. The hydrogenation of nitrobenzene to aniline has been performed using the catalytic membrane as an active gas-liquid contactor. Some operating parameters controlling the membrane reactor performance have been explored and compared with the behaviour of conventional reactors.
