The new ammoxidation catalyst （m-509） and the catalyst used in industrial fluidized bed reactor of m-xylene to produce m-dicyanobenzene has been characterized by XPS, ICP. It is showed that a lot of carbon existed on the surface of the catalyst that had been used in industrial fluid bed reactor for six months. The main reason of the catalyst deactivation was the loss of the active components. The carbon existed on the surface of the used catalyst has little effecton the activity of the catalyst. 催化剂失活 催化剂表征 氨氧化 间苯二腈 deactivation of catalyst characterization of catalyst ammoxidation m-dicyanobenzene O643.3 2001-04-01 2021-04-01 4
