Реферат:
Alumina desiccants obtained by extrusion molding of plastic pastes based on pseudoboehmite or
bayerite-containing hydroxides including those modified by sodium and potassium ions were studied. The
hydroxides were synthesized by hydration of the product of centrifugal thermal activation of gibbsite under
mild conditions. The physicochemical and structural-mechanical properties of the desiccants (fresh and after
nine adsorption–regeneration cycles) were studied. The dynamic capacity was determined at a pressure of
3 MPa under conditions designed to model the industrial conditions. The sample obtained from bayeritecontaining
hydroxide had a higher dynamic capacity than the sample obtained from pseudoboehmite-containing
hydroxide at close texture and strength characteristics of adsorbents. Modification of the samples
obtained from pseudoboehmite-containing hydroxide with potassium and sodium ions leads to decreased
granule stability and increased volume, average pore size, and dynamic capacity. The potassium-modified
sample of the desiccant had dynamic capacity as high as that of the sample obtained from bayerite-containing
hydroxide at low load. After the cyclic tests, the phase composition, alkaline impurity contents, specific surface
area, and crushing strength of the samples did not change within the error of determination. It was found
that the prepared desiccants were highly stable in many adsorption–desorption cycles and the minimum dew
point of –80°C could be reached during the drying.
