ABSTRACT:
Alumina-containing acid adsorbents and process for producing same. The adsorbents comprise activated alumina and an amorphous alkali (preferably sodium) aluminum silicate. The ratio of Si:Al in the amorphous material is preferably 0.25-100:1 by weight. A process for producing such adsorbents comprises treating activated alumina with a solution of an alkali metal silicate followed by an alkali metal aluminate, and forming agglomerates of the treated alumina at a temperature below about 90.degree. C., aging the agglomerates at a temperature in the range of 20.degree.-90.degree. C., and calcining the aged agglomerates at a temperature in the range of 200.degree.-500.degree. C. The adsorbent can be used to remove acidic materials from gases and liquids during industrial processes.
