Abstract: Reactive sorber is a flow sorption column for purification of gases at pressures till hundreds of bars by way of chemical capturing of impurities by metallic powder reactant (6). The powder is continuously rubbed in the process of mechanical stirring and is sorted with the help of a filtering divider (8) into two fractions, activated particles and exhausted material (12). The latter is removed into a waste collector (11, 13), which has a level meter calibrated in the units of purity of the gas exiting from the sorber.

Abstract: A method for preparation of a getter material on the basis of intermetallic compounds of barium is described. The method comprises preparing a melt of a ternary mixture containing barium, metal and sodium; directionally solidifying the melt to produce a textured ingot; granulating the textured ingot, thereby obtaining granules having open-ended voids extending therethrough; and evaporating the sodium from the granules by applying a thermovacuum treatment to the granules. The textured ingot comprises a getter body made of intermetallic compounds of barium; and open-ended voids within the getter body.
