It has http://bbs.hcbbs.com/thread-250099-1-1.html on it
Hydrogen-rich conditions refer to a temperature >250°C and a hydrogen partial pressure >1.4 MPa. This article states that the hydrogen partial pressure is >1.7 MPa.
Hydrogenation processes generally refer to reaction processes that involve the use of hydrogen, such as hydrorefining, hydrocracking, and hydrogenation-based dewaxing； Non-hydrogen processes generally refer to reaction processes that involve only catalysts without the use of hydrogen; common examples include non-hydrogen dew point reduction and non-hydrogen modification of gasoline and diesel.
Reply to 4# zhiyuan1100: I just want to ask about the knowledge related to the aspect you answered, rather than purely the metrics; it would be great if you could provide more detailed information.

Strengthen the equipment management of hydrogen-handling systems effectively, and conduct regular technical analyses and system leak inspections for issues such as hydrogen corrosion and hydrogen embrittlement in equipment operating under high-pressure hydrogen conditions. Upon identifying any issues, address them immediately to ensure everything is in good condition and meets the standards. 2. Before introducing hydrogen or filling a device or system with hydrogen, it must be purged and displaced using inert gases such as nitrogen or by water injection to remove air, until the system samples pass the analysis requirements.
