| Abstract: | A new type of non chrome catalyst R 120 for the oxidative dehydrogenation of n butenes to butadiene was studied and 500 hours stable test was performed in a φ 20mm quartz baffle fluidized bed reactor.As compared with the results of H 198,W 201 and R 109 performances in a φ 20mm quartz baffle fluidized bed reactor,R 120 exhibited the best results of butene conversion and selectivity to butadiene.According to the results,the relationship between the ratio of oxygen to butene and the amount of O 2 consumption was discussed in detail. The XRD patterns of fresh and used R 120 catalyst show that it has the stable bulk structure.Also the results imply that R 120 catalyst has an improved redox performance. |
