<p>The solid reactant (23), e.g. manganese or other chloride, in a graphite supporting structure, resting on - opt., above - the pressure vessel floor (30), includes diffuser(s) (26) for the gaseous reactant (22) - e.g. ammonia. A peripheral space (D) 1 to 10 mm wide, round the solid body, is filled with the thermally conductive, non-reactive heat transfer fluid (24), which is readily diffused by the gas. A suitably shaped shroud (25) contains the transfer fluid when the solid reactant expanding during the exothermic phase, raises the fluid level.</p> |
