(624e) Synthesis of Egg-Shell AuPd@SiO2 Catalysts for Liquid Phase Hydrogenation Reaction of Chloronitrobenzen to Chloaniline
AIChE Annual Meeting
Thursday, November 1, 2018 - 9:28am to 9:50am
In this study, egg-shell Pd-Au were supported on spherical SiO2 with 5 mm size. Using special technique, one was able to prepare a very thin shell. The catalysts were characterized by OM, TEM, HRTEM, and XPS. The catalyst was tested for liquid phase p-chloronitrobenzene hydrogenation reaction at 298 K, 0.55 MPa H2 pressure in a Carberry reactor. The catalyst was very active under pore-diffusion controlled regime if the shell thickness was very thin.
