满足净化系统的要求。

Abstract

The purification of krypton and xenon from the helium carrier gas of high temperature gas-cooled reactor by fixed bed activate carbon adsorption is studied. Experimental data at different adsorptive temperature

concentration

flow rate and bed depth are obtained from isothermal adsorption tests in order to examine the effects of these parameters on adsorption dynamic and for the optimal parameters selection of adsorption process. The results show that krypton and xenon from the helium carrier gas in HTGR can be eliminated by the coconut putamina activated carbon to meet the demands of purification system.
