METHOD FOR PRODUCTION OF PARA-HYDROGEN, CATALYST FOR ITS REALIZATION AND METHOD FOR PRODUCTION OF CATALYST Russian patent published in 1997 - IPC

FIELD: production of para-hydrogen by low temperature conversion of ortho-hydrogen. SUBSTANCE: hydrogen comprising ortho-hydrogen is contacted with molded catalyst, the process is carried out at cryogenic conditions at volume rate 4-4.5 1·10⁴h^-1. Said catalyst is promoted with hydrated oxides having common formula FeMe(OH)₃ or FeMe(OOH) where Me is molybdenum, tungsten, chromium, vanadium, and cobalt within definite concentrations. Catalyst is prepared by adding equinormal aqueous solution of sodium hydroxide into 2-6 N solution of ferrum (III) chloride, the process is carried out at 288-303 K. Then thus prepared sol of ferrum (III) oxide is mixed with slime of anode dissolution of steel at their ratio 1:(0.5-1) as calculated for ferrum. Thus obtained precipitate is formed, washed against sodium and chlorine ions, decanted, formed and activation. Said activation takes place at hydrogen flow at 373-423 K. EFFECT: improved output of reaction capacity unit, improved activity and strength of catalyst, decreased duration of forming of precipitate of catalyst. 4 cl, 1 tbl
