Abstract:
1. A system for production of aniline from nitrobenzene, the system comprising: at least one high shear mixing device configured for producing a dispersion of hydrogen gas bubbles in a liquid medium comprising nitrobenzene, wherein the dispersion has a mean bubble diameter of less than about 1.5 μm; a pump configured for delivering a feed comprising the liquid medium and hydrogen gas to said high shear mixing device, wherein the pump is fluidly connected to the at least one high shear mixing device via a conduit; a gas inlet line configured for introducing a dispersible gas comprising hydrogen into said conduit; and a pressure vessel configured for receiving said dispersion from said high shear mixer and comprising an outlet, and wherein the pressure vessel is configured to provide sufficient operating conditions for an exothermic catalytic reaction of nitrobenzene to form aniline.
