A Submerged Ceramic Membrane Reactor for the p-Nitrophenol Hydrogenation Over Nano-Sized Nickel Catalysts
The catalytic hydrogenation of p-nitrophenol to p-aminophenol over nano-sized nickel catalysts was carried out in a submerged ceramic membrane reactor. It has been demonstrated that the submerged ceramic membrane reactor is more suitable for the p-nitrophenol hydrogenation
over nano-sized nickel catalysts compared with the side-stream ceramic membrane reactor, and the membrane module configuration has a great influence on the reaction rate of p-nitrophenol hydrogenation and the membrane treating capacity. The deactivation of nano-sized nickel is mainly
caused by the adsorption of impurity on the surface of nickel and the increase of oxidation degree of nickel.
