摘　　要：The TS-1 life in propylene epoxidation was studied in a continually slurry reactor under the condition of 40 ℃ and 0.4, 0.6 MPa. It is suggested that the single circle life of TS-1 was no less than 80 h, the conversation of hydrogen peroxide was over 90%, the selectivity of propylene oxide and 1-methoxy-2-propanol was above 92.1%. The TS-1 catalyst can be regenerated in methanol, the initial activity of regenerative catalyst can’t change after the slightly deactivation in first regeneration. Element C and Ti were analyzed by XPS. The new the shift of electronic binding energy showed that Ti had been lost and deactivated in reaction, much carton deposited on the surface of TS-1, which are the main reasons of TS-1 deactivation, and the continual propylene epoxidation can be realized integrated with the thermodynamic reactor and the proper process.The TS-1 life in propylene epoxidation was studied in a continually slurry reactor under the condition of 40°C and 0.4, 0.6 MPa.
