The 300,000-ton-per-year coal tar deep-processing project involves a total investment of RMB 290 million; construction commenced in March 2021, and successful feedstock commissioning was achieved in April 2022. Major facilities include coal tar distillation, washing and decomposition, industrial naphthalene distillation, modified asphalt production, underwater asphalt pelletizing systems, raw material and finished product storage areas, and supporting environmental protection and public utility facilities. Annual output includes: 162,000 tons of modified asphalt, 74,200 tons of mixed anthracene oil, 33,200 tons of industrial naphthalene, 19,500 tons of wash oil, 5,400 tons of phenol oil, and 2,000 tons of light oil. Modified asphalt can be used to produce needle coke and carbon fiber, serve as raw material for prebaked anodes in aluminum electrolysis, or function as electrode binder; anthracene oil serves as feedstock for carbon black production or for crystallization to produce refined anthracene and carbazole; industrial naphthalene is utilized in manufacturing phthalic anhydride, dyes, resins, and other products; wash oil is primarily employed in benzene recovery within the coking industry or for further processing to extract related substances; phenol oil is used to manufacture engineering plastics; and light oil serves as solvent or feedstock for benzene hydrogenation.  
The second project—the 2,800-ton-per-year refined anthracene and 1,200-ton-per-year carbazole project—involves a total investment of RMB 120 million; construction commenced in March 2022 and commissioning occurred in April 2023. It uses anthracene oil produced by the aforementioned 300,000-ton-per-year coal tar deep-processing project as feedstock and employs China’s most advanced proprietary technology—the only green, environmentally friendly anthracene-carbazole production process currently operational in China—achieving both green production and green products. Key facilities include anthracene oil crystallization units, industrial anthracene rectification units, refined anthracene and carbazole concentration units, raw material and product storage areas, supporting public utility and auxiliary facilities, and environmental protection facilities. Refined anthracene can be oxidized to produce anthraquinone, a synthetic intermediate for medium- and high-grade dyes; high-purity anthracene can also serve as a semiconductor material in nuclear physics applications; carbazole is primarily used to manufacture high-end organic pigments (e.g., permanent violet), various dyes, and related intermediates.
