In a novel thermally coupled reacto

In a novel thermally coupled reactor, the naphtha reforming,
which is an endothermic reaction, was coupled with hydrogenation
of nitrobenzene to aniline to use its generated heat as a heat
source [125,126]. Co-current mode of operation for coupled reactors
is presented in Fig. 6. In this setup, the first two reactors in
the packed-bed configuration have been substituted with the highly efficient recuperative reactors. Catalytic reforming takes
place in the shell side whereas the exothermic hydrogenation of
nitrobenzene to aniline, which provides the heat for reforming process,
occurs in the tube side.
Catalytic naphtha reforming has also been coupled with hydrodealkylation
of toluene in a fixed bed reactor [127].
As mentioned, fluidized bed reactors have been used widely in
the chemical and petroleum industries because of their numerous
advantages. Coupling of the naphtha reforming and hydrogenation
reaction of nitrobenzene to aniline is also investigated in a fluidized
bed reactor [128].
