Preparation of TS-1 Monolithic Catalysts and Activity Evaluation for Cyclohexanone Ammonization Reaction

Abstract:

The Titanium silicalite-1 (TS-1)/cordierite monolithic catalysts prepared by wash coating-method were investigated by means of experiments in which we discussed the effects of TS-1 mass fraction in slurry, coating times and solvent viscosity on loading amount and adhesiveness. The results of cyclohexanone ammonization in self-made recirculating reactor showed that the activity and stability of TS-1 monolithic catalysts supported on cordierite honeycomb were better than traditional TS-1 powder in slurry reactor.
