      [ Chemical Machinery Equipment Network Industry News ] In order to promote carbon peaking and carbon neutrality in an orderly manner, as China's main energy source, low-carbon, clean and efficient use of coal is imperative

      A few days ago, the full text of the "Guiding Opinions on Promoting the High-quality Development of the Petrochemical and Chemical Industry during the 14th Five-Year Plan" jointly compiled by the Ministry of Industry and Information Technology, the National Development and Reform Commission and other six departments was released, requiring "to promote the high-end, diversified and low-carbon development of the coal chemical industry.
    According to the requirements of ecological priority, water-based production, total amount control, and agglomeration development, the modern coal chemical industry will be developed in a stable and orderly manner

    .

     

      At the same time, in order to give full play to the advantages of carbon fixation and consumption, it is necessary to speed up the demonstration of the coupling of refining, coal chemical industry, and “green power” and “green hydrogen” industries, and use refining and coal chemical equipment to discharge carbon dioxide with high purity and low capture cost.
    and other characteristics, and carry out demonstrations of large-scale carbon dioxide capture, storage, oil displacement, and chemical production

    .

     

      Coincidentally, the "Implementation Guide for Energy Conservation and Carbon Reduction Transformation and Upgrading in Key Areas of High Energy-consuming Industries (2022 Edition)" released at the beginning of the year also mentioned the energy saving and carbon reduction transformation of the modern coal chemical industry, and aimed at coal-to-methanol, coal-to-olefin and coal-to-ethanol.
    Diols put forward requirements: by 2025, the proportion of production capacity above the energy efficiency benchmark level in these three key directions will be 30%, 50%, and 30%, respectively

    .

     
    "Implementation Guidelines for Energy Conservation and Carbon Reduction Transformation and Upgrading in Key Areas of High Energy-consuming Industries (2022 Edition)"
      At the end of 2021, the Ministry of Ecology and Environment revealed that it will formulate and revise the environmental assessment and access specification documents for the "two high" industries, including the environmental access conditions for modern coal chemical construction projects, in stages and in batches, and guide the "two high" projects in the low-carbon and green transformation.

      As analyzed in the document, China's modern coal chemical industry has problems such as the coexistence of advanced and backward production capacity, and the significant differences in energy efficiency among enterprises
    .
    In terms of energy consumption, shortcomings such as insufficient utilization of waste heat, low level of process heat integration, and low energy efficiency of steam/power-consuming equipment still need to be filled, and there is great potential for energy-saving and carbon-reducing transformation and upgrading

    .

     

      However, considering the actual situation, the demand for special fuels and new chemical materials is still strong.
    Under the guidance of the market, the production capacity of the coal chemical industry will naturally increase.
    In order to develop its low-carbon development, it should be gradually implemented to avoid the emergence of "one size fits all".
    situation

    .
    In practical applications, many coal chemical companies have promoted clean production and green production by optimizing processes and coupling with clean energy to achieve quality and efficiency improvements

    .

     

      At this stage, there are two main paths for coal chemical industry to achieve low-carbon production, one is process emission reduction, and the other is combustion emission reduction
    .
    The former can use carbon oxide capture, utilization and storage technology to synthesize CO2 produced by coal chemical industry to produce chemicals, and realize resource utilization; the latter is to produce green hydrogen by introducing clean electricity.
    The coal-to-liquid chemical industry is coupled with a complete set of technical processes, and the process carbon emissions of coal chemical projects can be reduced by 95%

    .

     

      As early as 2018, the Chinese Academy of Sciences proposed a feasible solution for the low-carbon development of coal chemical industry, that is, a low-carbon composite energy system and its system integration , which couples nuclear energy, renewable energy and coal resources, and achieves carbon dioxide reduction while ensuring the supply of energy strategies.
    emissions, and provide solutions for low-carbon and efficient utilization of coal

    .

     
    Low carbon composite energy system and its system integration
      In short, coal chemical industry is the main application field of coal, and promoting its development towards a lower carbon and more efficient direction through technical means plays an important role in accelerating the green transformation of China's energy
