In petrochemical and petroleum refining industries, the hydrogenation technology is widely used. As materials used in key equipment, such as hydrogenation reactors, are subjected simultaneously to the action of hydrogen and high temperature, studies on material property degradation and remaining life predicting are very important with engineering and academic significance. An in service test block taken inside of the hydrogenation reactor DC 101A was examined. Material properties of 2.25 Cr 1Mo steel after service of about 10 5 h at the operating pressure of 17.47 MPa and temperature of 427 °C was obtained, including the embrittlement status, tensile, Charpy impact, and fracture toughness tests. Test results were compared with those obtained by experiments on another test block from the same reactor after 4.3 ×10 4 h service. Relationship between reactor material properties and operating time was discussed.
