The storage of liquid hydrogen has become much less troublesome as a result of regularly producing 85 percent para-liquid instead of ``normal.'' An ordinary liquefaction plant was modified so that the ortho- to para-conversion is catalyzed in the feed gas (at 76°K) and in the liquid within the liquefier. The liquid-phase conversion causes the full liquefaction rate to drop from 25 to 20.5 liters/hour. Data were also obtained for other liquefaction rates, with and without feed-gas catalysis.
