The 2 million tons project has been suspended, and 8 demonstration projects have been completed, with a total production capacity of nearly 10 million tons of coal-to-liquid "the road is long"

my country's coal-to-liquid production capacity

Coal-to-liquid is a technology that converts coal into petrochemical products such as gasoline, diesel, ethylene, etc.
through chemical processing and production.
The main method is to directly or indirectly hydrogenate coal to convert it into mixed hydrocarbon liquid fuel.
Or methanol.
Coal-to-liquid products are highly clean fuels with low levels of chemical components such as sulfur, nitrogen, and aromatics, and the proportion of harmful substances in combustion products is small.
Because of its advantages such as high calorific value, low freezing point, and low weight, it is widely used in military and civil aviation aircraft, especially for rocket and aircraft experiments under extreme weather conditions.
Indirect liquefied oil products are also used as cleaning agents.
Mixing them with ordinary fossils and diesel can effectively improve oil quality and reduce pollutant emissions.

After more than 20 years of technology research and development and industrialization promotion, China has made great achievements in the field of coal-to-liquid technology research and development and industrialization implementation, with the National Energy Group 4 million tons / year indirect coal liquefaction and 1 million tons / year direct coal liquefaction The Yitai 1 million tons / year fine chemicals project is a representative industrial demonstration project.
At present, there are 8 coal-to-liquid projects in China, as shown in Table 1 .

At present, most of my country's large-scale coal-to-liquid projects are concentrated in the northwest region.
The abundant coal resources in these places are conducive to the long-term development of enterprises.
Coal chemical projects are mostly constructed in a centralized and large-scale layout, such as the Ordos Coal Chemical Industrial Zone that has formed, and the Xinjiang Zhundong Coal-to-Liquid Industrial Base.

Coal-to-liquid development proposal

The coal-to-liquid process technology effectively supplements my country's petroleum resources, which is conducive to giving full play to the advantages of my country's coal energy, reducing the dependence of my country's petroleum energy on foreign countries, and ensuring the strategic security of my country's petroleum resources.
However, compared with petrochemicals, coal-to-liquid has a higher investment cost, consumes a lot of hydropower resources in production, and the huge amount of greenhouse gas emissions make the coal-to-liquid industry face many challenges.
Especially in the coal-to-liquid production process, there are still many problems, such as the low efficiency of coal-to-liquid gasification, high investment costs, and low oil quality.
Therefore, it is necessary to further strengthen the research of coal-to-liquid technology, accelerate technology optimization, and improve gasification efficiency and production efficiency.

At present, the economy of the coal-to-liquid industry is not optimistic.
Although the competition situation is complicated and challenging, it is also full of opportunities and motivation for upgrading.

On the one hand, my country's high oil dependence and complex geopolitical environment have not changed with the decline of international oil prices.
As a strategic reserve, the coal-to-liquid industry still needs to continue to exist and develop.

On the other hand, the coal-to-liquid industry can realize the clean conversion of coal, give full play to the raw material properties of coal to extend the coal industry chain, so as to effectively maintain coal consumption when the demand for fossil energy declines, and play a positive role in boosting the local economy.

Under the background of the current energy and chemical industry structure, coal-to-liquid companies should be driven by innovation, timely adjust their development strategies, further improve production processes, break through technical difficulties, increase the development of clean fuels and other breakthroughs, and become more refined and high-end.
Only with the development of globalization and differentiation can we have the ability to win a place in the global market.
