摘　　要：在实验室流化床评价装置上，评价了丙烯氨氧化制丙烯腈XYA-5催化剂的性能，并与同类型先进C-49MC催化剂进行了负荷对比实验。结果表明，在氨烯质量比为1．15-1．20、空烯质量比为9．3—9．5、催化剂负荷（丙烯与催化剂的质量比）为0．08～0．09、反应压力为0．06MPa、反应温度为430～440℃的条件下，丙烯转化率大于97％，丙烯腈收率大于81％，XYA-5催化剂表现出与C-49MC相近或略优的催化性能。The performance of catalyst XYA -5 for the preparation of acrylonitrile by propylene ammoxidation was evaluated in a test unit of fixed fluidized bed reactor,and the catalyst was compared with an advanced similar catalyst C - 49 MC at different loading level. The results showed that under the conditions of mass ratio of ammonia to propylene 1.15 - 1.20, the mass ratio of air to propylene 9.3 - 9.5, catalyst load（the mass ratio of propylene to catalyst）0.08 - 0.09, reaction pressure 0.06 MPa and reaction temperature 430 -440℃ , the propylene convertion and acrylonitrile yield were more than 97% and 81% respectively. Compared with catalyst C - 49 MC, XYA -5 catalyst exhibited similar or slightly superior reaction performance.
