| 摘 要： | A study on catalytic dehydration of 4-hydroxy-3-hexanone （HH） to 4-hexen-3-one （HO） was carried out through conversion of HH over HZSM-5 zeolite catalyst in a fixed-bed reactor （FBR） operating under almospheric pressure. The test indicated a relatively high activity of the HZSM-5 zeolite capable of achieving a HH conversion of 99.2% and a HO yield of 83.5%. Catalyst deactivation could be prevented by increasing the reaction temperature by 10 ＂C for every 20 h and adding 2.0% of piperidine in the feed. A catalyst stability test （for 100 h） in FBR showed that the catalyst was active even after 100 h of time-on-stream with HH conversion remaining at 99.2% and HO yield still reaching over 83.5%. Regenera- tion experiment showed that the regenerated catalyst demonstrated a catalytic performance comparable to the fresh one.
