Removal of Nitrogen from Hydrogen with Silica Gel at Low Temperatures
This paper gives the results of about twenty full scale purification tests made on the silica gel purifiers installed in the large CEL-NBS hydrogen liquefier for final purification of electrolytic hydrogen. These results are compared with predicted capacities made by W. T. Ziegler of the Georgia Institute of Technology, The increasing interest in purification of hydrogen for many uses, including liquefaction, prompted this evaluation program.
