On June 11, the pyrolysis phase of this demonstration project was successfully brought online, enabling the production of high-quality coal-based diesel and naphtha. The Yulin chemical pyrolysis project was completed on October 30, 2022. After 7 months of preparation for commissioning, it successfully carried out all the necessary preparatory steps – including thorough inspections and adjustments, purging and pressurization, individual unit tests, nitrogen integrity testing, hydrogen integrity testing, and catalyst sulfidation – and proceeded from feeding materials into the system to the successful production of high-quality coal-based diesel and naphtha, with the entire process proceeding safely and efficiently. It is reported that the pyrolysis pilot project is China’s first industrial demonstration facility of a million-ton scale for coal pyrolysis on a single production line. By removing oil and extracting gas from coal, this project enables efficient utilization of resources, increases the proportion of H and C elements in coal that end up in downstream products, thereby improving overall energy efficiency and reducing carbon emissions. This project has successfully established a new low-cost, high-efficiency route for producing aromatic compounds from coal, which will play a key role in promoting the simultaneous \"differential development\" and \"integration\" of coal chemical industry, petrochemical industry, and polymer materials. By producing chemical products alongside specialty oils, it is possible to generate chemicals in normal times and oil in times of war, offering a brand new chemical solution from Yulin to ensure **energy security**. The 15 million tons per year demonstration project for the clean and efficient conversion of coal into various products by Yulin Chemical Company is located in the Qingshui Industrial Park of the Yushen Industrial Zone. It is capable of processing over 24 million tons of coal each year. The project is constructed in two phases and four stages, comprising 27 process units along with associated utility systems. These include low- and medium-temperature pyrolysis of 15 million tons of coal, production of 5.6 million tons of methanol, 1.8 million tons of ethylene glycol, 2 million tons of MTO, as well as downstream products derived from these intermediates. The pyrolysis startup project mainly includes a 1.2 million tons per year pulverized coal pyrolysis unit and a 500,000 tons per year coal tar hydrogenation complex. It is constructed simultaneously with Yulin Chemical’s first-phase 1.8 million tons per year ethylene glycol plant, utilizing Shengbang Technology’s own pyrolysis technology ； In the second phase, the scale of pyrolysis will be increased to 15 million tons, and the coal tar industry chain will be expanded to produce aromatic hydrocarbons as well as downstream products derived from arylenes. The Yulin Chemical 15 million tons/year demonstration project for the clean and efficient conversion of coal based on different quality grades is implemented in two phases; the first phase involves the construction of an ethylene glycol production facility with a capacity of 1.8 million tons per year, as well as a pyrolysis pilot plant. The total investment for the two-phase project is approximately 201.4 billion yuan; it is a super-large-scale modern coal chemical industry project. Building on the infrastructure developed in phase one, this project will involve the construction of facilities for producing olefins, aromatics, and other products through efficient sorting and grading of coal. These basic products will then be further processed to yield four categories of end products with high added value: high-value materials, battery electrolyte solvents, biodegradable materials, and special oils. This approach aims to achieve coordinated development between the coal chemical and petroleum chemical industries.
