Investigation Of Breakthrough Curve Of 10K Cryogenic Adsorber In Helium Refrigerator

High pure quality helium is required in helium refrigerator and cryogenic adsorber is essential in cryogenic engineering system, while there is a lack of cryogenic adsorption data below 20K which causes inconvenience when it comes to the design of cryogenic adsorber. The paper mainly deals with the design of a 10K cryogenic adsorber in a helium refrigerator which works at 250W@4.5K. Isothermal and nonlinear dispersion plug flow model is built to investigate the breakthrough curve of trace hydrogen with helium being the carrier gas. It can help in lateral design of cryogenic adsorber.
