Methane decomposition properties of ZrNi alloy in flowing gas system

With the intention of developing the decomposition process of tritiated compounds, ZrNi alloy was taken up as one of proper materials and its methane decomposition properties were experimentally investigated in a laboratory-scale flowing gas system. Methane was selected as a typical tritiated compound because of being known to be hardly decomposed and little data. The performance tests of methane decomposition using ZrNi alloy under various process conditions of gas flow rates (20, 35, 70 and 100 cc min −1), granular sizes (70–200, 200–400 and
