Question: For a diesel hydrogenation reactor made of 12Cr2Mo, what are the requirements regarding temperature and pressure increases in a hydrogen-rich environment?

The pressure increase shall not exceed 15 kilograms per hour, and the temperature rise shall not exceed 20 degrees per hour； As the reaction temperature is approached, the heating rate can be reduced

The chemical engineering design manual also requires a hydrogen erosion curve diagram for the ammonia synthesis process; it seems to be called a Nelson curve diagram. I estimate it’s fine to use this chromomoly steel at 400 degrees.
