摘　　要：实验室开发出新型SANC-08丙烯腈合成催化剂,在反应温度440℃、反应压力0.084 MPa、催化剂负荷0.06 h^(-1)、n(空气):n(丙烯)=9.5和n(氨气):n(丙烯)=1.25反应条件下,丙烯转化率97%以上,丙烯腈选择性82%以上,丙烯腈收率大于80%,氨转化率94%以上。流化床反应器稳定性试验结果表明,2 177 h时,丙烯腈收率78.9%,丙烯转化率94.6%,丙烯腈选择性83.3%。A new acrylonitrile synthesis catalyst, SANC-08, was developed. Propylene conversion of over 97%, selectivity to acrylonitrile of over 82%, acrylonitrile yield of over 80% and ammonia conversion of over 94% were obtained under the following condition ： reaction temperature 440 ~C, reaction pressure 0. 084 MPa, catalyst loadings 0. 06 h -1, n （air） ： n （propylene） = 9.5, n （ ammonia ） ： n （propylene） = 1.25. The stability test showed that acrylonitrile yield of 78.9%, propylene eonversion of 94.6% and selectivity to acrylonitrile of 83.3% were attained after operation for 2 177 h.
