Effects of nitrogen on hydriding of a titanium particle bed

Nuclear fusion is one of the most promising means not only for a primary energy source in the future, but also for the production of hydrogen as a secondary energy source by utilizing its heat generation. The plan is proposed that deuterium and tritium hydrogen isotopes are supplied into a plasma chamber for nuclear fusion and the gas exhausted from the chamber is recovered with a metal particle bed. In this study, titanium particles with a size of ∼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 investigated. It was found that titanium gives a high capacity for hydrogen recovery even in the presence of nitrogen.
