From May 11–12, 2019, a review meeting on the overall design of the 2000,000 tons/year coal-based clean fuel project in Bijie, Guizhou was held at Beijing Zhongke Synthetic Oil Engineering Co., Ltd. The project owner, Guizhou Yufu Energy Development Co., Ltd., invited 17 industry experts, as well as a total of 90 participants from 6 relevant design firms including China Aerospace Changzheng Chemical Engineering Co., Ltd., Air Products (China) Investment Co., Ltd., Beijing Wanbonda Environmental Protection Technology Co., Ltd., China Power Construction Group Guizhou Electric Power Design Institute Co., Ltd., Southwest Municipal Engineering Design Institute Co., Ltd., Keyang Environmental Engineering (Shanghai) Co., Ltd., and Beijing Huayu Engineering Co., Ltd., to attend the meeting for review purposes. The review committee conducted a special assessment of the overall project layout, gasification and purification, oil synthesis and processing, utility systems, as well as technical economics. The experts reviewed the selection of the main technical approaches for the overall layout, the main process flow schemes, and the research on specific projects, provided corresponding suggestions and opinions regarding the overall design, and approved the overall design of the project in principle. Next, the overall design contractor, Zhongke Synthetic Oil Engineering Co., Ltd., will further optimize the overall design plan based on the suggestions from the expert group and the organizations that participated in the review meeting, thereby laying a solid foundation for the project’s basic design and detailed design. Project Overview: I. Project Owner and General Information on the Project Project Owner: Guizhou Yufu Energy Development Co., Ltd. Project Name: 2 million tons per year coal-based clean fuel project in Bijie, Guizhou Construction Location: Nayong County Coal, Electricity, and Chemicals Integration Industrial Base, Shabao Town, Nayong County, Bijie City, Guizhou Province. Guizhou Yufu Energy Development Co., Ltd. is a joint-stock company established under the leadership of Chongqing Yufu Asset Management Group Co., Ltd.; it was founded in August 2008 with a registered capital of 500 million RMB. Its business scope includes coal chemical processing, mineral product sales, and non-financial investments. On April 16, 2014, the project received the \"Reply from the General Office of the National Development and Reform Commission regarding the preliminary work for the 2 million tons per year coal-based clean fuel project in Bijie, Guizhou\" (Document No. Development and Reform Office Energy ﹝2014﹞819). From the end of 2016 to the beginning of 2017, the **National Development and Reform Commission** and the **Energy Administration** issued the \"13th Five-Year Plan for Energy Development\" and the \"13th Five-Year Plan for the Development of Advanced Coal Processing Industries\" respectively. These plans designated the project in Bijie, Guizhou as a key project for advanced coal processing and coal-to-oil production during the 13th Five-Year Plan period; it was also one of the four new projects to be launched during that time. The project makes use of the high-temperature slurry bed process technology independently developed by Zhongke Synthetic Oil Technology Co., Ltd. It employs the coal-to-oil technology developed by this company, a technology that has received joint support from the \"863\" Program’s project on \"indirect coal liquefaction\" as well as from the Chinese Academy of Sciences’ major knowledge innovation project focused on the research and development of industrial slurry bed technologies for coal-based liquid fuels. This technology has passed the technical evaluations conducted by experts organized by the Ministry of Science and Technology and the Chinese Academy of Sciences, thereby laying a technical foundation for the establishment of industrial demonstration plants. Currently, the original high-temperature slurry bed process technology has been validated at the Yitai and Lu’an demonstration plants. The key core technologies behind its major breakthroughs include: a unique high-temperature slurry-bed iron-based catalyst technology (with a production capacity 4 to 6 times that of the international standard), large-scale high-temperature slurry-bed Fischer-Tropsch (F-T) reactors and related equipment technologies, as well as integrated process technologies for F-T synthesis and oil product processing. Through the actual operation of two pilot plants, it has been demonstrated that the advantages of this technology include: a catalyst activity of 1.0–1.4 GC3+/g catalyst/hour (compared to around 0.3 for traditional methods), as well as a significantly reduced operating cost for the process ； The product shows excellent selectivity ； The structure of the large-scale slurry-bed F-T synthesis reactor and the design of its reaction system are reasonable. The operation results of the demonstration plant show that the Fischer-Tropsch synthesis unit is the most stable system in the entire plant, enabling it to effectively buffer and mitigate operational fluctuations in other units and prevent the shutdown of the whole plant ； The steam generated as a by-product in the Fischer-Tropsch synthesis unit can have a pressure of 2.0 Mpa to 2.5 MPa, and can be directly used for saturated steam power generation, thereby further improving the energy efficiency of the process.
