Study of sorption properties of HF 512O and NaX synthetic zeolites in the process of sorption of air mixture components

Abstract

The sorption properties of synthetic zeolites HF 512O and NaX were studied. In the course of the study, the volume method obtained the sorption capacities of zeolites for nitrogen and oxygen. The experimental setup for determining the sorption capacity by volumetric method consisted of two tanks. The first tank has a known volume, and the second tank is filled with the studied sorbent. Helium was used to determine the free volume of the second tank. The gas sorption capacity of which must be determined is fed to the first tank, the second tank is pumped out using a vacuum pump, after which the tanks are connected and the separation in the tanks is leveled. Thus, the sorption capacity of the sorbent can be calculated based on the pressure drop in the system. The selectivity of sorbents for the nitrogen – oxygen pair for pure gases was calculated.
