HYDROGENS PURIFICATION OF METHANE ON HOT URANIUM BEDS

Hydrogen's purification of methane has been investigated for applicati on to fuel clean-up. After describing the experimental means, results are given as a function of main operational parameters before establis hing a process model and its validation. Then a conception of a DT pur ification prototype is proposed as an application. Globally, the resul ts show that high purification efficiencies can be performed insofar a s the uranium bed temperature is sufficiently high (> 800-degrees-C) f or obtaining acceptable reactional kinetics between methane and uraniu m. Finally several potential applications to a Fusion Tritium Plant ar e envisaged.
