Title: Adsorption apparatus
IPC: B01D53/04
Filed: 1943-09-06
Abstract: 576,727. Adsorption apparatus. COMMONWEALTH ENGINEERING CO. of OHIO. Sept. 6, 1943, No. 14588. Convention date, Aug. 27, 1942. [Class 1 (i)] An adsorber comprises a cylindrical vessel provided with a plurality of equidistantly spaced rectanguler beds radially disposed from a common centre and having perforated side walls for the passage of the vapour-containing air or gas through the beds in transverse direction. In the adsorber illustrated in horizontal cross-section in Fig. 3, 10 is the cylindrical shell of the adsorber and 40 is a concentrically disposed cylindrical member. The beds consist of an outer perforated plate, 15, faced on the inside with a wire mesh screen, 16, against which the adsorbent, 17, is held. The end plates of the cylinder 10 which support and cover the beds, also act as distributing plates. In, for example, the extraction of acetone from air, the acetoneair mixture enters the bottom portion of the adsorber and passes, via the bottom distributing plate into the quadrant 32 and 33, through the beds. The residual air passes into the other two quadrants and thence via the top distributing plate out of the adsorber. During desorption steam is passed in the opposite direction. After steaming, the beds are dried and/or cooled by passing air through them from the bottom. When used for removing moisture from air or from a gas such as carbon monoxide, using silica gel or activated alumina as the adsorbent the beds are dried and cooled by passing warm and cool air successively through them from the top.

Abstract: Silica-clad metal oxide sols are prepared by adding to an organic silicate to a metal oxide sol and heating the mixture to hydrolyse the silicate while maintaining the pH above the isoelectric point of silica, i.e. above about pH 2-3 depending on silica concentration. Specified metal oxides are thoria, urania, plutonia and thoria-urania, and specified organic silicates are alkyl silicates having 1-3 carbon atoms in the alkyl groups, preferably tetra ethyl orthosilicate.  The heating is preferably performed by heating under reflux, and the pH maintained by adding a weak anion exchange resin. The final sol is preferably stabilized by addition of a base, sodium hydroxide being exemplified, to a pH of 7-9,5.  In the first example a thoria sol of pH 4,6 having spherical particles 70 mm  in diameter is prepared by electrodialysis (see Group XXXVI) and concentrated to 12% ThO2 and a density of 1,13.  Ethyl orthosilicate and water are added and the mixture refluxed with stirring.  The pH fell to 2,2, sodium hydroxide was added to increase the pH to 9 and the sol evaporated to concentrate, autoclaved at 150 DEG C., passed through a cation exchange bed, the pH adjusted to 8 and the sol concentrated to a density of 1,5, a pH of 7,9 and a conductance of 6.14 X 10-4 mhos/cm.  In a second example, a similar thoria sol was treated with ethyl orthosilicate and anion exchange resin added during refluxing.
