Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】A continuously updated summary thread – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On September 24, 2025, a conference on the achievements in aerospace biomass gasification technology, themed “Integrating Intelligence with Biomass for New Carbon Solutions,” was held in Cangzhou, Hebei Province. The reporter learned at the meeting that the \"integrated technology for the carbonization, pulverization, and gasification of aerospace biomass\" released this time was independently developed by Aerospace Changzheng Chemical Engineering Co., Ltd. (referred to as \"Aerospace Engineering\"). It has recently passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation (referred to as \"CPCIF\"]), marking a new stage in the industrial application of high-efficiency conversion technologies for biomass energy using fluidized beds in China. Behind the achievement of this technology lies not only the urgent need for a transformation in China’s energy structure, but also a vivid demonstration of the aerospace industry’s commitment to independent innovation and the pursuit of breakthroughs in key manufacturing processes. This three-year-long technical achievement has successfully transformed biomass from being used in low-value combustion processes into high-value chemical raw materials, providing a practical solution for optimizing China’s energy structure and protecting the ecological environment. It also offers an industrializable approach that facilitates the green transformation of this industry. The energy transition calls for efficient conversion of biomass energy. Against the backdrop of China’s comprehensive efforts to transform its energy structure into one that is cleaner, lower in carbon emissions, and more efficient, biomass energy, as a high-quality resource that is both renewable and capable of reducing carbon emissions, has not been able to realize its full potential due to issues such as low conversion efficiency and difficulties in industrialization. It is said that currently, opportunities and challenges coexist in the energy transition. On the one hand, new energy development in our country is progressing rapidly. Since the 14th Five-Year Plan period, China has established the largest and fastest-growing renewable energy system in the world, with renewable energy power generation accounting for around 60% of the total ； On the other hand, rules such as the EU’s Carbon Border Adjustment Mechanism are reshaping international green trade, and standard systems for international green methanol and green aviation fuel are putting certain pressure on China’s industries. Meanwhile, domestic new energy policies continue to promote the utilization of new energy sources and the development of related infrastructure; the industry chain involving green electricity, green hydrogen, and green alcohol is rapidly taking shape, thereby providing a broad market opportunity for the development of biomass energy. Against this backdrop, the breakthrough in integrated aerospace biomass carbonization, pulverization, and gasification technology comes at just the right time. Jiang Congbin, chairman of Aerospace Engineering, stated: “The coal chemical industry, as a key emission-intensive sector, faces clear constraints on emission reduction as well as pressure to transform.” Biomass gasification coupled with coal chemical engineering is a viable approach to achieving system carbon reduction under current technical conditions. By integrating a ‘biomass end’ with a ‘coal end’ and making use of the existing infrastructure in the industrial park, this technology adopts a ‘two-ends-one-end’ approach that not only helps to reduce carbon emissions throughout the entire life cycle but also provides a valuable opportunity for traditional chemical parks to revitalize their assets and make a smooth transition toward carbon neutrality. ” Based on the internationally leading aerospace powder gasification technology, this technique further optimizes the carbonization and powder production process. Yin Yutian, General Manager of the Hydrogen Energy Division of Aerospace Engineering, noted that this technological achievement solves the problem of low-cost, low-power powder production in fluidized bed systems, reducing the overall energy consumption in the carbonization powder production process by approximately 25% compared to traditional carbonization techniques. At the same time, this technology effectively avoids the bonding problem of alkali metals and solves the issue of corrosion caused by high-chloride gray water. This technology enables the methanol production cost for typical projects to be kept between 3,200 and 3,400 yuan per ton, offering significant economic viability. The data from the pilot scale phase provided strong support for the feasibility of the technology. Fang Hua, deputy director of the Aerospace Engineering Process Piping Department, disclosed the key operational data of the pilot plant: China’s first integrated pilot plant for biomass carbonization, powder production, and gasification with a processing capacity of 1.0 t/h has operated for over 300 hours in total, and it functioned safely and stably during 72 hours of continuous operation tests. Specific data show that the mass yield of biochar (on a dry basis) is 88.8%, while the energy yield of biochar is 92.2% ； At a gas pressure of 3.0 MPa, the carbon conversion rate was 98.6%, the content of useful gases (CO+H₂) was 80.6%, and the cold gas efficiency was 74.1%; all these values met or exceeded the design specifications. On September 21, at the scientific and technological achievement evaluation meeting organized by Sinopec, the evaluation committee composed of seven industry experts unanimously agreed that the integrated technology for the carbonization, pulverization, and gasification of aerospace biomass is feasible and meets the conditions for industrial application. They approved the evaluation and recommended accelerating its industrial demonstration use. Zhang Wenbin, deputy head of the Thermal Engineering Department of the aerospace industry, explained that this technology has enabled the creation of the first pilot-scale installation in the industry that combines \"carbonization for powder production with fluidized-bed gasification.\" Tests related to coal grinding for powder production, dense-phase transportation, and high-pressure gasification have been carried out in detail, with a total operating time of over 300 hours. Under the same carbonization conditions, this device achieves the maximum conversion of energy and carbon into useful gas, avoids the problem of alternating hot and cold temperatures in the material, and enables optimal utilization of energy; it is particularly suitable for large-scale biomass carbonization.
