Recently, with the successful output of needle coke from the first tower of the new carbon material production unit, it was marked that Shandong Hengxin Group’s project for producing 100,000 tons per year of new carbon materials and making use of high-temperature coal tar has been successfully commissioned from the start. The project utilizes Baosteel Engineering’s proprietary improved solvent process to effectively remove impurities from the raw materials, producing refined asphalt with extremely low levels of quinoline insolubles. This approach improves the quality of needle coke at its source. The refined asphalt is then subjected to pyrolysis and condensation reactions through a delayed coking process to produce needle coke, which is subsequently removed using closed-loop coke removal technology, thereby enabling green and environmentally friendly production. In addition to producing high-quality needle coke, it also generates by-products such as coking gas, heavy oil, and light oil. These by-products are sent to companies within the group for hydroprocessing, thereby enabling resource recycling and maximizing the value of tar resources. At present, the entire production system is operating stably, and the product quality is excellent. Every effort is being made to advance the preparations for pilot production in the subsequent stages; the full operation of the Hengxin New Materials project will undoubtedly inject strong momentum into the high-quality development of the regional new materials industry.
