... solvents. The removal from these solutions of high molecular weight impurities is entirely dependent on the quality of active carbon (AC) used for cleaning. On the other hand, AC wastes are disposed in damps, which deteriorates both the economy ofthe desulfurization process and creates the problems of pollution of the lithosphere. The authors conducted the evaluation of new high-strength AC for cleaning amine solutions and developed a technology forcoal reactivation, allowing its repeated use in this ...
