Annotation

This study explores the suitability of beneficiated Uzbek coal as a feedstock for gasification and pyrolysis processes. XRF analysis of the unprocessed coal indicated a high concentration of inert, ash-producing minerals, while SEM imaging showed a compact structure with minimal porosity. GC-MS analysis of the resulting fuel confirmed the presence of key hydrocarbon components. Overall, the results indicate that treated coal offers high efficiency and low residue, making it well-suited for modern fuel conversion applications.
