The industrial structure of blue carbon needs to be optimized, and the application prospects in the field of blast furnace injection are good.

Blue charcoal, also known as semi-coke, is a solid carbon product obtained by medium-low temperature carbonization pyrolysis of low-rank coal lump coal as raw material. As a new type of carbon material, blue carbon has the advantages of high chemical activity, low aluminum/sulfur content, and high fixed carbon. It has been widely used in calcium carbide, chemical industry, ferroalloy and other fields. In the future, as environmental protection requirements increase, the market application demand for blue carbon will further increase.

According to the “2023-2027 Blue Carbon Industry Market In-depth Research and Investment Prospect Forecast Analysis Report released by the Industrial Research Center, my country The layout of the blue charcoal industry chain is relatively complete. In recent years, with the continuous release of my country’s market demand, the output of the blue charcoal industry has continued to increase. According to data from the China Coal Processing Industry Association, my country’s blue charcoal output will be approximately 65.5 million tons in 2022. Blue charcoal production is highly concentrated, with the combined output of Yulin, Shaanxi and Hami, Xinjiang accounting for approximately 90%. In addition, blue charcoal is also produced in Tangshan, Hebei, Ordos, Inner Mongolia, northern Shaanxi, Ningxia and other regions.

my country’s blue charcoal industrial system is complete, and has now formed multiple integrated industrial chains such as “coal-blue charcoal-power generation”, “coal-blue charcoal-magnesium metal”, “coal-blue charcoal-carbide-carbide-polyvinyl chloride”. However, due to unstandardized management and slow iteration of technology/equipment updates, my country’s blue carbon industry is still facing problems such as overcapacity in mid- to low-end production and environmental pollution. In the future, the structure of the blue carbon industry still needs to be continuously optimized. Scale, environmental protection, and high output value are the key issues. The future direction of blue carbon industry upgrading.

Blue charcoal production companies include Shaanxi Coal and Chemical Group Shenmu Tianyuan Chemical Co., Ltd., Shaanxi Shuangyi Coal Chemical Technology Industrial Co., Ltd., Inner Mongolia Zhengneng Chemical Group Co., Ltd., Fugu Jingfu Coal Chemical Co., Ltd., Jianglvster Energy Co., Ltd., Inner Mongolia Wanzhong Weiye Technology and Environmental Protection Co., Ltd., etc. my country’s blue charcoal industry is large-scale, and its production capacity not only meets domestic market demand, but also exports to overseas markets such as Japan and Malaysia.

Blue charcoal has obvious advantages in cost, performance, economy, energy, etc., and can replace coke in ferroalloys, calcium carbide and other fields. In addition, blue charcoal also has broad application prospects in blast furnace injection, activated carbon, carbonaceous reducing agents and other fields. In the field of blast furnace injection, blue carbon replaces anthracite, bituminous coal, etc., which can optimize the resource structure of blast furnace injection raw materials and reduce carbon dioxide emissions. In recent years, many steel companies, including Baosteel, Anshan Iron and Steel, Nanjing Iron and Steel, Baotou Iron and Steel, etc., have carried out research and experiments on blue carbon injection in blast furnaces.

Industry analysts said that as a new carbon material, blue carbon has excellent performance and high cost performance. It is widely used in ferroalloys, calcium carbide, chemical industry, etc. The field of application is broad. my country’s blue carbon industrial system is complete, but there is excess production capacity in the middle and low-end. Blast furnace injection of blue carbon can not only solve the current overcapacity problem of blue carbon, but also help to reduce costs and increase efficiency in the steel industry, in the strategy of carbon neutrality and carbon peaking. Against this background, the application of blue carbon in the field of blast furnace injection is expected to continue to deepen.
