Coal-to-high-carbon alcohol can achieve clean utilization of coal resources. my country’s technological research continues to deepen

High carbon alcohol, also known as higher fatty alcohol, refers to a mixture of monohydric alcohols with more than six carbon atoms. Coal-based high-carbon alcohol, also known as coal-based high-carbon alcohol, refers to high-carbon alcohol produced from coal as raw material through clean conversion. In recent years, with the accelerated development of the coal chemical industry, my country’s coal-to-high-carbon alcohol technology has continued to make breakthroughs, and the product application prospects continue to improve.

The high-carbon alcohol industry has high technical barriers. There are only a small number of companies with large-scale production capabilities in my country, and demand is highly dependent on imports. Against this background, my country’s coal-to-high-carbon alcohol industry is taking advantage of the momentum. Using coal as raw material to produce high-carbon alcohols can effectively realize the clean utilization of my country’s coal resources and is of great significance to the development of the coal chemical industry. my country is a major coal producer. According to data from the National Bureau of Statistics, my country’s raw coal output will reach 4,495.839 million tons in 2022, a year-on-year increase of 9%. The advantages of raw materials have laid a good foundation for the development of my country’s coal-to-high-carbon alcohol industry.

According to the “2023-2028 China Coal-to-High Carbon Alcohol Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that the technical routes of coal-to-high-carbon alcohol include direct synthesis of synthesis gas, Fischer-Tropsch paraffin method, α-olefin synthesis and coal-to-olefins method. The direct synthesis gas synthesis method is the mainstream technical route for producing high-carbon alcohols from coal. It first converts coal gas into synthesis gas, and then uses a catalyst to modify it, and finally produces high-carbon alcohols; the coal-to-olefins method uses coal as raw material and uses methanol to produce olefins. The device produces alpha olefins, and finally high-carbon alcohols are produced through chain extension treatment. This method has the advantages of being green, environmentally friendly, safe and reliable, and can be used to produce specific high-carbon alcohol products.

In recent years, Chinese enterprises and scientific research institutions have continuously increased their investment in research and development of coal-to-high-carbon alcohol technology and have made many new progresses. The Dalian Institute of Chemical Physics, Chinese Academy of Sciences, has long been focused on the research of coal-to-liquid catalysts and processes. Currently, the carbon-supported cobalt-based catalyst independently developed by Ding Yunjie’s research team has been widely used in the production process of high-carbon alcohols and liquid hydrocarbon chemicals. In March 2023, Ningxia University’s “Coal-based Applied Catalysis” innovation team used Fe-Cu co-modified Co3O4-based catalysts to successfully convert high-carbon alpha-olefins into high-carbon alcohols.

Shanghai Huanqiu, Yili Energy, Yinuo New Materials, Yulin Coal Chemicals, Ningxia Coal Industry, etc. are the main producers of high-carbon alcohols from coal in my country. Yulin Coal Chemical is one of the earliest companies in my country to conduct research on coal-to-high-carbon alcohol technology. In 2019, it cooperated with the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, to complete the world’s first coal-to-high-carbon alcohol industrial test.

Industry analysts said that coal-based high-carbon alcohol has the advantages of sufficient raw material supply, safety and environmental protection, and is expected to become my country’s high-carbon alcohol in the future. Main preparation methods. In recent years, thanks to the improvement of independent research and development capabilities of local enterprises and related scientific research institutions, my country’s research on coal-to-high-carbon alcohols has made many new progress. In the future, with the continuous improvement of technological maturity, the development speed of my country’s coal-to-high-carbon alcohol industry will further accelerate.
