Abstract

1309611 Removing HF from gases VEREINIGTE ALUMINIUM-WERKE AG 4 Jan 1971 [21 Jan 1970] 358/71 Heading C1A HF is removed from gases by contact at room temperature to 150‹ C. with solid Na aluminate, an alkali metal oxide-containing alumina having a molar M 2 O/A1 2 O 3 ratio exceeding 0À5, or mixtures thereof. The process may be operated in a packed column with particles of size 3-6 mm., or in a fluidized bed or in countercurrent flow with particles of size 1-3 mm.
