Abstract

This study investigates the thermal dissolution of bituminous coal to produce extracts suitable for manufacturing of high-quality carbon materials, particularly carbon binders and needle coke. The research focuses on the composition and properties of coal extracts, their distillation fractions, and the structural features of the resulting carbonized products. The extracts exhibited low benzo(a)pyrene levels, making them environmentally favorable compared to traditional feedstock for coal tar pitches manufacturing. Distillate fractions obtained from these extracts primarily consisted of aromatic hydrocarbons. Carbonized products derived from the distillates are predominantly composed of turbostratic structures, with a minor proportion of well-ordered graphite-like domains. The study confirms that the choice of solvent for coal dissolution critically affects both distillate yield and final coke quality. Structural characterization against reference data demonstrated that the distillate obtained from coal extract in a mixture of coal tar and heavy cyclic oil yielded a coke with a morphology most similar to standard needle coke.
