Description

The invention relates to a pressure vessel activated, fossil silicic acid or hydrated lightly used for liquefied gas combined with an alumina in its interior, with filled adsorbent, powdery carrier, on the portion of the precipitated pure silica between which the liquefied gas is distributed. Is 35 25 ° and 50 ° / ₀ by weight of the mixture.

In such a pressure vessel, the precipitated pure silica preferred here consists of the

Disadvantage that solid particles of the adsorbent carrier is a very fine and very light, white amophes of the powder flowing out through the open discharge valve, its physical properties preferred gas are carried away and the narrowest cross-section are wisely the following:
