Abstract
A hydrogen liquefier is described in which the hydrogen is condensed at 6.6 atmospheres by means of liquid neon produced in a Joule‐Thomson liquefier. This cascade liquefier produced and consumed 17 liters/hour of liquid neon and produced 27.5 liters/hour of liquid hydrogen, representing an increase of 6 to 20 percent over direct Joule‐Thomson liquefaction of hydrogen. Means are described whereby further increase in yield and ease of operation could be achieved. Owing to some mechanical difficulties, the elimination of which would mean major construction changes, the system was abandoned in favor of the original Joule‐Thomson method.Keywords
