Study about sorption in sponge and powder titanium of hydrogen isotopes obtained from a cryogenic distillation process

Hydrogen absorption kinetics of porous Ti6Al4V alloys

“…The hydrogen absorption rate is larger than the desorption rate with increasing temperature leading to the decreasing trend of hydrogen pressure. Compared with those in literatures [23,24], the starting temperature of hydrogen absorption in porous Ti6Al4V alloys is lower than that in dense Ti6Al4V alloys but higher than that in Ti6Al4V powders. When the temperature is above 823 K, the pressure increases again with increasing temperature, as section CD shown in Fig.…”

Preparation of Pd Membrane Supported on Al₂O₃ Nanofiber Nonwoven Used in Hydrogen Separation

“…Hydrogen can be purified through several techniques such as pressure swing adsorption (PSA) [2,3] , cryogenic distillation [4] , and membrane separation [5,6] . PSA and cryogenic distillation processes are commercially available processes but they are energy intensive process.…”

“…4 Cl (Tianjin Northern TianYi Chemical Reagent Plant, China) was dissolved in 8mL NH 3 OH (28%) (Tianjin No.3 Chemical Reagent Plant, China) under stirring to prepare the solution. The two kinds of solution were added into 50mL distilled water, and let stand for 24h.…”
