Investigation of the effect of cyclical loading by pressure on the resource and sorption characteristics of the composite sorbent

The paper is aimed to an experimental study of the effect of multiple cyclic pressure loading on the resource and sorption characteristics of a composite sorbent with microspheres selectively permeable to helium as a filler and pseudobemite as a binder. To conduct the resource tests, an experimental stand was designed and manufactured that allows to simulate various operating modes of gas separation facilities in the operating pressure range up to 10 MPa. For the composite sorbent, cyclic pressure loading tests with control measurements of the sorption capacity of the sorbent with respect to helium were carried out. It is shown that under conditions of multiple cyclic loading at pressures up to 10 MPa, the composite sorbent retains its structural integrity and sorption characteristics.
