IMPROVING THE TECHNOLOGY OF PREPARATION OF THE ADSORBENT UZ-AD-1 BASED ON THE SPENT ADSORBENT SGCC, INCLUDING THE STAGE OF MODIFYING COMMERCIAL CARRIERS

Abstract

Due to the combination of thermal stability, the ability to control the pore structure, resistance to dripping moisture, commercial availability and the availability of raw materials for the production of aluminum oxide from natural minerals (bauxite, nepheline, alunite), etc. active alumina is one of the most common adsorbents. Aluminum oxide, both in pure form and after modification, is widely used for drying various gases and removing many types of other polar impurities [1, 2]. Its important consumer property is also resistance to multiple cycles of "adsorption-thermal desorption".The set of requirements for activated alumina is determined by the specific features of the processes in which it is used, however, among the many modifications of alumina, it is most often used as an adsorbent. γ-Al2O3.
