摘　　要：长期处于高温、高压、临氢环境下运行的加氢反应器 ,其材质会出现回火脆化和氢脆等现象 ,对设备安全运行构成威胁。本文通过对R4 0 1加氢精制反应器内置 2 2 5Cr- 1Mo挂片的解剖 ,分析该反应器运行 35 0 0 0h后的回火脆化量 ,并对冲击试样进行电化学充氢试验 ,分析充氢对2 2 5Cr- 1Mo钢的脆性转变温度的影响 ,从而为加氢反应器的安全运行提供借鉴。The materials of hydrogenation reactor working under high temperature high pressure and hydrogen environment will be damaged of temper embrittlement and hydrogen embrittlement, which will threaten the working in safety of the reactor. In the paper, based on a series of tests for the service materials of R401 hydrogenation refining reactor that have been working about 35000 hours, the temper embrittlement of 2.25Cr-1Mo steel have been studied. The method of electrochemical hydrogen charging was applied to study the hydrogen effect on the brittle transition temperature, it provide a reference basis for the hydrogenation reactor working in safety.
