Abstract

1,174,889. Inorganic substances. W. R. GRACE & CO. 21 May, 1968 [24 May, 1967], No. 24240/68. Heading B1E. [Also in Division C1] Al 2 O 3 is added to a reaction mixture comprising M AlO 2 (M is alkali metal), which is preformed or formed in situ by reaction of MOM and Al 2 O 3 , and (NH 4 ) 2 CO 3 or CO 2 , preferably in the presence of water, to form dawsonite M Al (CO 3 ) (OH 2 ) having unreacted Al 2 O 3 dispersed throughout: The mixture is dried at at least 250‹F and then heated to 400-2000‹F to effect conversion to an alkalised alumina containing at least 70% of Al 2 O 3 ) which may be used as adsorbent for H 2 O, H 2 S, SO 2 and acidic gases.
