| Abstract: | The key procedures to prepare Pd supported on activated carbon catalysts in the hydrogenation of benzoic acid,and reasons for the deactivation of Pd/C catalyst and its solving methods are described respectively in this paper according to the theory of hydrogenation reaction of benzoic acid. It is showed that the longevity of Pd/C catalyst can be prolonged by adding methanation promoter, and the deactivation can be regenerated by supercritical fluid extraction. |
