Vacuum-desorption method for separating the H-2 + D-2 isotope mixture using a quantum ortho-para-conversion process at hydrogen temperature

摘要

The effective evacuation and separation (at helium temperature) of a model gas mixture consisting of He, H-2, D-2, N-2, Ar and other components (close to that formed in a thermonuclear reactor) yielding up to 44% of D-2 during desorption, is implemented using a newly developed vacuum pump-separator with a non-isothermal multilayer (up to 100 layers) system of working elements (consisting of perforated screening and spacing materials). Improvements to the vacuum-pump separator design and the use of an ortho-para conversion catalyst made it possible to increase the yield of D-2 from the model mixture to 64-69% at hydrogen temperature.
