Heavy Oil:
  Carbon black is primarily used as a reinforcing agent in the rubber industry—for both tires and automotive and non‑automotive rubber components—where it significantly enhances strength and mechanical properties. The main feedstock used for producing this material is tar‑based heavy oil grade CB‑OH12.
  At Coal Tar Refining Company, the required feedstock is sourced from coking units and petrochemical complexes. This feedstock is processed in refinery distillation units under fully controlled conditions and separated into light, medium, and heavy fractions. The heavy oil used for producing CB‑OH12 is obtained from the heavy fractions of this process.
  The final product undergoes rigorous quality control testing in the company’s fully equipped laboratories to ensure full compliance with international standards and the technical requirements of customers.
  Applications:
  • Used as raw material in the manufacturing of carbon black for tires and plastics.
  • Used in the production of industrial bitumen and protective coatings.
  •  Used as a carbon source in the synthesis of CNTs, especially in the CVD process.
  • Used in GTUD production as a graphitized carbon source to stabilize and uniformly disperse nanodiamonds within a conductive and heat-resistance matrix.
  • Used as an initial feedstock in chemical plants and for producing additives.
  • Used as a precursor for carbon fiber production.
  • Used as a carbon source in the production of Fullerenes via electric arc or laser evaporation method.
  •  Used as a carbon source to make carbon dots in nanotechnology.

Light Oil
  Coal Tar Light Oil is one of the primary fractions obtained from the distillation of coal tar, collected within the lower boiling range. This fraction is mainly composed of light aromatics dominated by benzene and mono‑alkylated derivatives, and due to its purity and stability, it is considered a valuable feedstock for downstream industries.
  As a key raw material, Coal Tar Light Oil—after separation and hydrotreatment processes—provides the benzene and ethylbenzene required for the production of Styrene Monomer (SM). Its structural characteristics make it highly suitable for use in the styrene value chain as well as in other aromatic products.
  This product is manufactured and quality‑controlled in accordance with international standards and is available for use in units producing aromatic chemicals, resins, and intermediate chemical products.
  Applications:
  • Chemical feedstock for the production of plastics, resins, adhesives, solvents, synthetic fibers and dyes.
  • Wood protection against biological degradation, decay and insect infestation. 
  • Gasoline blending additive to improve fuel performance and reduce pollutant emissions.
  • Utilized in the synthesis of various chemicals including emulsifiers, surfactants, and agricultural chemicals.
  • Employed as a solvent in degreasing and metal cleaning processes.
  • Serves as a carrier solvent in pesticide and fertilizer formulations in agriculture.

Solvent Naphtha:
  Industrial solvent is processed from a relatively light fraction of coal tar distillate oil. The feedstock used in the production of this solvent is supplied from coking units and petrochemical facilities, and it is separated into light, medium, and heavy fractions in refinery distillation units under precise and controlled conditions. Solvent Naphtha is extracted from the medium fractions and then further purified through additional refining steps.
  The final product undergoes comprehensive quality‑control testing in advanced, well‑equipped laboratories to ensure that key parameters such as flash point, water content, stability, and chemical composition fully comply with international standards and customer specifications. This solvent serves as an essential material used across a wide range of industrial applications.
   Applications:
  •  Used as strong solvent in the production of industrial paints and coatings.
  •  Used as a raw material for industrial resins.
  •  Used as an aromatic carrier and dispersing agent in agrochemical formulations.
  •  Used as a solvent in printing inks.
  •  Used as an intermediate in synthesis of aromatic chemical compounds.
  •  Used as a solvent in the formulation of industrial adhesives and sealants.
  •  Used as a cleaning agent in industrial degreasing processes.
