Abstract:
A method of preparing cyclohexanone by hydrogenating phenol is provided. The method includes a step of introducing an additional flammable gas to dilute hydrogen gas concentration, so as to increase the throughput and decrease energy consumption. Further, the discharged residual gases from the hydrogenation of phenol have a calorific value. Also provided is a system for generating cyclohexanone by hydrogenating phenol.
