    摘要: There is diclosed a process for purifying hydrogen gas which comprises removing impurities such as nitrogen, oxygen, methane, carbon monoxide, carbon dioxide and moisture contained in a crude hydrogen gas by bringing the crude hydrogen gas into contact under heating with a hydride of a zirconium alloy such as Zr-V, Zr-V-Ni, Zr-V-Cr, Zr-V-Co, Zr-V-Fe, Zr-V-Cu, Zr-V-Ni-Cr, Zr-V-Ni-Co and Zr-V-Cr-Fe. By virtue of using the above Zr alloy hydride, the process enables highly advanced purification of crude hydrogen gas by removing such impurities as above to a level as low as 1 ppb or less in high safety and efficiency at low installation and running costs.

    摘要: A processing method of an exhaust gas which comprises a step (A) adding a halogen-based gas-absorbing liquid to an adsorbent and a step (B) bringing the exhaust gas containing a halogen-based gas discharged from semiconductor manufacturing facilities into contact with the adsorbent, to remove the halide-based gas from the exhaust gas. A processing apparatus of an exhaust gas, which comprises an inlet for the exhaust gas containing a halogen-based gas discharged from semiconductor manufacturing facilities, a filling part of an adsorbent, means for adding a halogen-based gas-absorbing liquid to the filling part and an outlet of the processed gas. A processing method and a processing apparatus both for an exhaust gas containing the halogen-based gas discharged from semiconductor manufacturing facilities without requiring to frequently replace a cleaning agent with a new one, without jeopardy of causing fire even when processing a dry exhaust gas containing a highly reactive gas, and capable of easily reducing a concentration of the halogen-based gas among the gas after being processed is provided.

    摘要: Highly purified rare gas (helium, neon, argon, krypton, xenon, etc.) is obtained by removing impurities contained therein, such as nitrogen, hydrocarbon, carbon monoxide, carbon dioxide, oxygen, hydrogen and water, at relatively low temperatures by the use of a getter. This getter is a two-component alloy of zirconium and vanadium, or a multi-component alloy containing, as well as zirconium and vanadium, at least one of chromium, nickel and cobalt.
