Hydrogen and diesel
Thread Content
What is the relationship between the solubility of hydrogen in diesel and temperature and pressure? Is the solubility higher at higher temperatures, or what?
Calculate it by yourself and you’ll remember it clearly
As the temperature increases, solubility increases； Solubility increases as pressure rises.
The higher the temperature, the greater the solubility; therefore, by controlling the temperature of the recycled hydrogen, and also by implementing a high-temperature fractionation process, hydrogen consumption increases indirectly – in other words, the hydrogen ends up going along with the low-temperature fractions or as waste hydrogen.
