A coal chemical project in Xinzhou, Shanxi, requiring an investment of 1.36 billion yuan, has been approved. Recently, the environmental impact assessment for Shanxi Yixin Energy Technology Co., Ltd.’s project for the comprehensive utilization of low-grade coal at a capacity of 3 million tons per year was approved by the Shanxi Provincial Department of Ecology and Environment. The project is located within the Yuanping Economic and Technological Development Zone in Xinzhou City (the initial phase of the Yuanping Circular Economy Industrial Park). It is capable of processing 3 million tons of low-grade coal per year, and it utilizes advanced domestic technologies for the selective utilization of low-grade coal through pyrolysis. The Fischer-Tropsch synthesis project uses coke oven gas as raw material, and through purification, conversion, and Fischer-Tropsch synthesis, it produces cobalt-based Fischer-Tropsch products, thereby developing a new method for utilizing coke oven gas. Shanxi Xinsi New Energy Technology Co., Ltd. was established in 2011, jointly invested by Shanxi Jinlong Energy Investment Co., Ltd. and Shanxi Fengneng Investment Co., Ltd. Shanxi Yixin Energy Technology Co., Ltd. is a wholly-owned subsidiary of Shanxi Xinsi Energy Technology Co., Ltd., and was established in May 2020. The first-phase project of Shanxi Yixin Energy Technology Co., Ltd., which involves the production of 2 million tons per year of metallurgical coke and coal chemical products, and the second-phase project focusing on the comprehensive utilization of low-grade coal at a rate of 3 million tons per year, cover a total area of 2,670 mu. The main products of the 3 million tons/year low-grade coal comprehensive utilization project include: 1.8 million tons/year of upgraded coal, 270,000 tons/year of tar, and 300 million Nm3/year of gas. The project processes 3 million tons of low-grade coal per year, utilizing state-of-the-art technologies for the differentiated utilization of low-grade coal to achieve comprehensive exploitation of this type of coal under mild conditions. The pyrolysis products are high-quality coal with improved properties, low-temperature coal tar with a high hydrogen-to-carbon ratio, and low-temperature pyrolysis gas with high calorific value. Through further processing of coal tar and pyrolysis gas, clean fuels such as gasoline, diesel, CNG (LNG) can be produced. The total investment for the 3 million tons per year low-grade coal comprehensive utilization project is 1.36 billion yuan, of which 44.46 million yuan is allocated to environmental protection measures. The main construction components include pyrolysis for quality improvement and gas purification; additional facilities such as phenol-amine recovery and salt extraction from desulfurization waste liquids are also included, along with corresponding auxiliary systems, storage and transportation facilities, utility systems, and environmental protection measures. Part of the purified gas is reused in the hot blast stoves, while the remaining portion is supplied to the 2.6 million tons per year alumina production project of **Power Investment Group Shanxi Aluminum Co., Ltd. as a clean fuel.
