DEVELOPMENT OF THE TECHNOLOGY OF PRODUCTION OF IMPORT SUBSTITUTION ADSORBENTS BASED ON LOCAL RAW MATERIALS

Abstract

The following work presents the results of the study of methods for producing effective zeolite and aluminum oxide adsorbents for the condensation of various process streams, including liquefied petroleum and other hydrocarbon gases using local mineral raw materials and industrial waste in exchange for imported ones. The study reveals that samples of synthesized zeolites obtained from enriched Angren kaolin using alkaline crystallization technology in granules without a binder have a good sorption capacity as per water vapor and can be recommended for drying gases that do not contain easily coking admixtures. The results of laboratory studies of the aluminum oxide adsorbent Uz-AD-1 have been proved by tests on real gas regeneration of the gasoline reforming unit of the Bukhara oil refinery. It is shown that the developed new domestic adsorbents are slightly inferior in the total capacity of HCl and Н₂О, to the currently functioning imported analogues, and may be used in the alternative.
