Abstract

The present research deals with forecasting the potential content of humic acids (HA) in Ukrainian lignite based on the coal’s physicochemical characteristics. The focus is on developing an experimental–statistical model that considers moisture content, volatile matter yield, and calorific value of lignite. The development of the humic acid yield’s dependence on some lignite parameters is based on both original research data and literature sources. Humic acids were extracted using alkaline solutions, and HA content was calculated for various lignite deposits in Ukraine. The adequacy check of the model showed a relative prediction error of up to 12%, indicating good agreement between the model and experimental data. The highest potential yield of humic acids was recorded for lignite from the Dnipropetrovsk region (Dnieper-Donets Basin), amounting to 53–56 wt.%. The presented results demonstrate the feasibility of using mathematical forecasting to assess the industrial potential of humic acid production from lignite.
