Abstract

The invention provides a testing device and method in a high-temperature and high-pressure hydrogen corrosion environment. The testing device comprises a high-temperature and high-pressure reaction kettle, a gas supply unit and a heating unit, the gas supply unit comprises a high-pressure pure hydrogen cylinder, a high-pressure pure carbon dioxide cylinder, a hydrogen booster pump and a carbon dioxide booster pump; a gas outlet of the high-pressure pure hydrogen cylinder is connected with a gas inlet of the high-temperature high-pressure reaction kettle through a hydrogen booster pump; a gas outlet of the high-pressure pure carbon dioxide cylinder is connected with a gas inlet of the high-temperature high-pressure reaction kettle through a carbon dioxide booster pump An exhaust port is formed in the high-temperature and high-pressure reaction kettle; the heating unit is used for heating the high-temperature and high-pressure reaction kettle. According to the system and the method, the corrosion condition of the material in a high-temperature and high-pressure hydrogen corrosion environment can be simulated, and the service safety condition of the metal material can be conveniently and efficiently evaluated.

Description

technical field [0001] The invention belongs to the technical field of high temperature and high pressure corrosion testing, and particularly relates to a testing device and method under high temperature and high pressure hydrogen corrosion environment. Background technique [0002] Hydrogen production from coal gasification will be the main technical route for the future hydrogen economy. Hydrogen production from supercritical water gasification is a very promising process for the efficient and clean conversion of coal. The State Key Laboratory of Power Engineering Multiphase Flow of Xi'an Jiaotong University invented "a supercritical water gasification hydrogen production device and method of coal with residual liquid recycling" (application publication number: CN106276788A). Regasification can not only improve the coal slurry Gasification efficiency, and can make the system close to zero emissions. [0003] Hydrogen atoms have high activity, and can form molecules once ...
