| Summary: | The paper is devoted to the problem of purification of gaseous fuels used in thermal power plants. It is not uncommon for stations to use gaseous waste from petrochemical enterprises as an additive to the main fuel as part of a resource-saving policy. However, natural gas and gaseous waste need to be pre-cleaned of sulfur compounds to reduce the operating load on equip-ment and reduce the negative impact on the environment. The purpose of this article is to devel-op and justify the choice of a sorption material with a high sulfur content and physical charac-teristics that meet the requirements of GOST. This goal is achieved through the implementation of the following tasks: analysis and selection of components of sorption materials based on TPP water treatment sludge, activation of waste from the plant's water treatment plant, preparation of complex compounds with different percentages of the main active substances, determination of the synergistic effect between the components of the composition. The most important results are the determination of the balance between an effective combination of components in a composition that provides a high sulfur content; the definition of a list of metal oxides that can increase the absorption capacity of sulfur compounds; the development of an adsorbent with a high sulfur content and acceptable physical characteristics. The significance of the results obtained lies in the fact that the proposed desulfurization method is not only economically feasible, but also environmentally beneficial due to the reuse of station waste. The conducted research has made it possible to expand knowledge in the field of purification of gaseous fuels from sulfur compounds and identify effective adsorbent components that increase sulfur capacity. |
