    Abstract: An adsorbable gas can be efficiently recovered by subjecting a gas containing the above gas at a low concentration to adsorption/desorption treatment in a first adsorption column packed with an adsorbent, and condensing a desorption gas, containing the adsorbable gas at a higher concentration, discharged from the column. In this process a desorption gas discharged from a second adsorption column is introduced into the first column wherein the adsorption has been completed to adsorb and desorb an adsorbable gas contained in the desorption gas and a gas discharged in the step of condensing the desorption gas and containing a noncondensed adsorbable gas is introduced into the second column to adsorb an adsorbable gas contained in the discharged gas, the adsorbed adsorbable gas being desorbed in the second column in the next adsorption/desorption cycle to give a desorption gas containing the desorbed adsorbable gas, which is discharged from the second column and introduced into the first column wherein the adsorption has been completed. This process is easy to operate and requires little thermal energy for desorption.

    Abstract: In an electrode in which electrode activating metal particles are applied onto an electrode core, a highly durable low-hydrogen overvoltage cathode characterized in that part or the whole of said electrode activating metal particles consists of a hydrogen-occluding metal which is capable of electrochemically occluding and releasing hydrogen. A method of producing a highly durable low-hydrogen overvoltage cathode characterized in that an electrode core is immersed in a plating bath in which hydrogen-occluding metal particles capable of electrochemically occluding and releasing hydrogen are dispersed at least as a portion of the electrode activating metal particles, to effect composite plating, so that said electrode activating metal particles are electroplated onto said electrode core together with the plating metal. A method of producing a highly durable low-hydrogen overvoltage cathode characterized in that a layer is applied by the baking method or the melt-coating method onto the electrode core such that part of the electrode activating metal particles is exposed on the surface of the layer, said layer containing hydrogen-occluding metal particles capable of electrochemically occluding and releasing hydrogen as part of the electrode activating metal particles. A method of producing a highly durable low-hydrogen overvoltage cathode characterized in that a sheet is prepared which contains hydrogen-occluding metal particles capable of electrochemically occluding and releasing hydrogen or which contains electrode activating metal particles consisting of said metal particles and another low-hydrogen overvoltage metal particles, in a manner that at least a portion thereof is exposed on at least one surface of the sheet, and the surface of said sheet opposite to the surface where said particles are exposed is adhered onto the electrode core.
