High Pressure Adsorption Isotherms of Neon, Hydrogen, and Helium at 76°K
The cryogenic engineer often is confronted with the problem of separating a gas mixture, or of removing undesirable trace components from a gas stream to be used in a refrigerator or a liquefier. When a physical adsorption process is used to achieve this separation or purification, a knowledge of the high pressure adsorption isotherms of the components in the mixture often is required. Unfortunately, very few measurements have been made on the adsorption of gases at pressures greater than 1 atm and at temperatures below 100°K. Only the limited measurements of Czaplinski and Zielinski , Knorn , and Cook  are available. The work presented here was undertaken to help fill the gap in the existing measurements.
