ABSORBENT FOR REMOVAL OF TRACE OXYGEN FROM INERT GASES

摘要

An adsorbent for use in removing trace oxygen from an inert gas comprises a porous reducing support, such as activated carbon, carbon black, coal, petroleum coke and titania, which is impregnated with an alkali metal oxide or an alkaline earth metal oxide formed in situ by thermal decomposition in an inert gas of an alkali metal salt or alkaline earth metal salt. <IMAGE>
