<p>The aim of the research is to study the formation of sodium aluminates - centers that are actively chemisorbed in acidic impurities consisting of powder components made from imported aluminum hydroxide and processed on alumina absorbent, with variations of the conditions of their alloying with the same amount of the sodium hydroxide. It was found that in the high temperature samples, the absorption properties and the suppression potential activity in undesirable side oligomerization reactions are determined by the amount of the formed Na7Al3O8 phase, and NaОН.Н2О and Na2СО3 in the pore volume. The granules processed on alumina adsorbent allow achieving the optimal combination of HCl adsorption volume and surface adsorption features without high temperature processing.</p>
