STORAGE OF LIQUID HYDROGEN

Abstract

A description is presented of three devices for catalytic conversion of ordinary liquid hydrogen into predominantly parahydrogen (up to 99.7%). The devices described are for use in conjunction with liquefying systems. The purpose of the conversion process is the extension of storage time for the liquid gas and the considerable reduction of storage losses caused by the heat of reaction of natural conversion of orthohydrogen to parahydrogen in the liquid state. The catalysts mentioned are dry hydroxides, such as Fe(OH)3, Cr(OH)3, and Mn(OH)4, and an industrial chromiumnickel catalyst (See: Boreskov, K. G., and M. G. Lin'ko. Khimicheskaya promyshlennost', no. 2, Feb 1956, 69). Schematic diagrams of the reactors are presented. (Author)
