Abstract

Environmental safety of industrial enterprises is one of the most important tasks, ensuring both high-quality preliminary preparation of gaseous fuel and purification of smoke emissions. Purification from sulfur compounds, such as hydrogen sulfide and mercaptans is most often carried out by the adsorption method using multicomponent materials. The authors have developed compositions of adsorption materials with the inclusion of solid waste from water treatment plants. Such compositions are distinguished by economic availability, increased resource conservation, and are also an ecological alternative to the disposal of industrial waste. As part of the work, the sulfur capacity of the developed compositions in laboratory conditions was determined, Langmuir and Freundlich adsorption isotherms were built for each composition, and the equilibrium constant. Based on the analysis of the data obtained, conclusions were made on the adsorption mechanisms for adsorbents
