Four trends of modern coal chemical industry in the future

is a relatively "rich coal and less oil" country in China. It is of strategic significance to develop modern coal chemical products properly and orderly. After years of hard work, China has developed and constructed modern coal chemical products, technologies and equipment, such as coal to oil, coal to olefin, coal to dimethyl ether, coal to ethylene glycol and coal to natural gas, etc., and has begun to take shape, laying a solid foundation for its further development.

and

are not so controversial as coal chemical industry, but this does not deny its importance. China's "lack of oil and gas, relatively rich in coal" resource endowment characteristics, determines that coal chemical industry will become an important pole of the chemical industry. Similarly, coal to oil and gas is an important part of China's "energy security strategy", which is of great significance to reduce China's oil and gas dependence on foreign countries and ensure national energy security. Zhang Jinyang, senior engineer of

and

Sinochem chemical fertilizer Co., Ltd., believes that the following four development trends of coal chemical industry are of particular concern. The coal chemical industry of

and

is an effective supplement to petrochemical industry. The relationship between

and

modern coal chemical industry and petrochemical industry is, in short, interdependent and complementary. Modern coal chemical industry can realize the partial, but not all, substitution of petrochemical products. The oil price of

and

is the key to the success or failure of modern coal chemical projects. It is meaningless to talk about the benefits of coal chemical industry without this "benchmark". Therefore, it is very important to control the scale of coal chemical industry.

and

at present, the advantages of coal chemical industry compared with petrochemical industry are mostly at the expense of environmental capacity and carbon emissions. Once these "free lunches" are not available, their competitive advantages will not be the same as those of petrochemical industry.

and

predict that by 2020, one third of the chemical products produced by petrochemical lines will be replaced by coal chemical industry, that is, in the competition with petrochemical industry, the ultimate goal of coal chemical industry is "one in three".

and

are bound to choose

and

to extend the coal chemical industry chain. Jin Yong, academician of Chinese Academy of engineering, proposed that "the direction of coal chemical industry is material rather than fuel", which is the inevitable choice for the development of coal chemical industry. Therefore, it is not advisable to encourage or support the transformation of coal from one fossil energy to another, such as coal to oil and coal to natural gas.

and

coal to liquid gas are transformed from one energy source to another, not to mention the energy conversion efficiency. Only excessive carbon emission is an insurmountable obstacle, so it is not suitable to be widely promoted. Before the carbon emission exceeding the standard has not been solved thoroughly, if the coal chemical industry is fully spread, it is undoubtedly "seeking the end by giving up the capital".

and

therefore, it is necessary to comprehensively summarize and evaluate the demonstration projects that have been completed and put into operation. The future trend of coal to liquid gas can only be determined based on the evaluation results.

and

specifically, in the product chain of coal to liquid, coal to alcohol and ether fuel, coal to olefin, coal to natural gas, coal to ethylene glycol, coal to aromatics and other product chains, the development of coal to olefins, coal to aromatics and coal to ethylene glycol should be given priority, but the overall scale should also be controlled.

and

extend the industrial chain and product chain is the eternal theme of coal chemical industry, and is also the most effective way to avoid and resolve the overcapacity of coal chemical industry. Without the support of downstream market, coal chemical industry will become "water without source and end without root".

the boundary between coal chemical industry and petrochemical industry is fuzzy.

in the future, the boundary between petrochemical industry and coal chemical industry may become more and more fuzzy. The two will gradually form a large chemical pattern of "you have me, I have you". The coupling and grafting between petrochemical and coal chemical industry will be the general trend.

and

realize the complete industrial chain of coal to polyethylene terephthalate (PET) through the coupling of coal to aromatics and coal to ethylene glycol, which will be a new investment hotspot in coal chemical industry. "Spkds" and "coal fine" and "coal chemical industry" will be concentrated in the "future". The former refers to the large-scale scale and production capacity, which is what we often call the industry access threshold, such as the annual production of 500000 tons of olefins, 2 billion cubic meters of natural gas and 1 million tons of coal to liquid; the latter refers to the fine differentiation of market and technology, that is, to increase the added value of conventional coal chemical products (such as methanol) by extending the product chain.

and

in addition, China's coal chemical industry will form two camps, one is the advantage of coal enterprises, such as Shenhua, China coal, Yitai, Henan energy, etc.; the other is the advantage of petrochemical enterprises, such as Sinopec, Yanchang oil, etc. Between the two camps. At present, the former is far ahead and should be equally divided in the future.
