EFFECTS OF NITROGEN ON HYDRIDING OF A TITANIUM PARTICLE BED

Nuclear fusion is one of the most promising means not only for a prima ry energy source in the future, but also for the production of hydroge n as a secondary energy source by utilizing its heat generation. The p lan is proposed that deuterium and tritium hydrogen isotopes are suppl ied into a plasma chamber for nuclear fusion and the gas exhausted fro m the chamber is recovered with a metal particle bed. In this study, t itanium particles with a size of approximately 100 mesh are packed in a column for recovery of hydrogen from an inert gas stream. The effect of nitrogen as an impurity on absorption capacities and rates is inve stigated. It was found that titanium gives a high capacity for hydroge n recovery even in the presence of nitrogen.
