Abstract
A description is given of an apparatus which utilizes the mechanism of preferential adsorption on alumina (Al2O3) at a temperature of 20 K to achieve the separation of the ortho species from the para species of molecular hydrogen. Enrichment of the ortho component occurs within a cylindrical adsorber column approximately 50 in long and 1 in in diameter. The column is cooled by heat exchange with circulating helium gas from a two-stage electrically driven cryogenerator, thereby eliminating the need for liquid hydrogen and nitrogen coolants. Large scale production of orthohydrogen is possible since the system is capable of continuous operation for indefinite periods, and supplies orthohydrogen gas of 99% purity at a rate of 3-4 litres (STP) per hour. The design and operation of the separator are discussed in some detail.
