摘　　要：介绍了轴径向和全径向变换反应器的结构特点。以国内分别采用轴径向、全径向结构的一段变换反应器为例,在一段变换反应器直径、催化剂型号和装填量、生产负荷完全相同的条件下,比较了在相同催化剂运行时长下,两种结构的变换反应器出口变换气中的CO含量及出口平衡温距。结果表明,由于变换反应器内装填的催化剂在运行过程中存在沉降现象,全径向变换反应器的催化剂利用效率比轴径向变换反应器的低,并存在气流易走“短路”的缺陷。为克服上述缺陷,建议大型变换装置优选轴径向结构的变换反应器。The structural characteristics of axial radial and full radial shift converters are introduced.Taking first-stage shift converters one with axial radial structure the other with full radial structure in China as an example,the CO content in outlet shift gas and outlet equilibrium temperature interval of the two structures of shift converters are compared under the same first-stage shift converter diameter,catalyst model and loading amount,production load as well as same catalyst operating time.The results indicate that due to the sedimentation phenomenon of the catalyst loaded in the shift converter during operation,the utilization efficiency of the catalyst in the full radial shift converter is lower than that in the axial radial shift converter,and there is a defect of easy"short circuit"of the airflow.To overcome the above shortcomings,it is recommended to choose axial radial structures shift converters for large-scale shift unit.
