Main direction of coal chemical enterprises: Fine Chemical Industry

After the development of

in recent years, the scientific research force of coal chemical enterprises in China is relatively strong. However, many researchers in coal chemical enterprises are doing the same task, such as cobalt and iron catalysts for Fischer Tropsch synthesis, catalysts for methanol dehydration to olefins and ethylene glycol hydrogenation catalysts. These problems and scientific research institutes seriously crash, the depth of research can not be compared with national scientific research institutes.

and

, but in sharp contrast, coal chemical enterprises are lack of scientific research in fine chemical industry, and most of the technologies for building fine coal chemical plants are imported. Taking the recently famous Yulin circular economy coal comprehensive utilization project as an example, the project takes coal as raw material, and produces 2180000 tons of fine chemical products through coal gasification, methanol to olefin / olefin derivatives and other devices. Among the 23 sets of chemical plants, 19 sets adopt foreign technologies, and more than 10 sets of fine chemical processes are all introduced.

and

are the consequences of abnormal development of coal chemical research. The equivalent of a high-speed rail train, one car is full of people, while the others are very few.

and

national research institutes are characterized by a small number of high-level talents. Their task is to solve the national problems, and the project is to meet the needs of the national public products and military products. Another characteristic is that their achievements must be promoted nationwide until the total production capacity meets the needs of the country. However, the demand for fine chemical products is not so large, and the technology transfer rate is not high in the case of marketization, so the national research institutes will not be very interested in this.

and

national scientific research institutes are rich in human resources and financial resources, with large scale and long time of scientific research. For example, Fischer Tropsch synthesis and methanol cracking to olefins have been done for decades, which is incomparable to the enterprises and institutes. Therefore, coal chemical enterprises should give up the idea of competing with national scientific research institutes, do the projects they don't do and focus on the development of fine chemical industry, so that the scientific research will have a bright future. The scientific research scale of

and

fine chemical products is small and the investment is small, so coal chemical enterprises can afford it. At the same time, there are many kinds of fine chemicals, and enterprises have more choices in scientific research, so there will be no phenomenon of "thousands of troops crossing a single tree bridge". Therefore, the research and development of coal chemical enterprises should avoid the competition with national scientific research institutes and develop towards fine chemical industry with small demand and many varieties.

and

coal chemical enterprises have syngas, and some enterprises have rich capacity of syngas. Therefore, coal chemical enterprises can make full use of the characteristics of syngas to produce oxygen-containing and oxygen-containing nitrogen compounds by carbonyl synthesis technology, and combine with large amount of polymer chemical materials, and gradually expand and extend coal chemical products from fuel type to fuel / chemical material combination type fine chemical green road. The carbonyl synthesis of

and

is also called hydroformylation. The reaction of olefin with carbon monoxide and hydrogen in the presence of catalyst, adding hydrogen atom and formyl to olefin double bond to form two isomeric aldehydes with one more carbon atom than the original olefin. Because the final product needed in industry is alcohol, the hydrogenation of aldehyde to alcohol is usually included in carbonylation synthesis. Therefore, carbonyl synthesis is one of carbonylation, and the other refers to the reaction of introducing carbonyl group into another molecule, such as carbonylation of methanol to acetic acid. Carbonyl products can be extended from alcohols, acids, esters, ketones, ethers, amides, acyl chlorides to the fields of chemical materials such as polycarbonate, polyester, polyketone and polyamide.

and

carbonyl synthesis products are very wide, most of the catalysts for carbonyl synthesis route are very mature in the world, and have a good industrial foundation. They can become a bridge between coal chemical industry (carbon chemical industry), petrochemical industry and natural gas chemical industry, so they are favored by international academic and industrial circles. The reaction substrates for carbonylation of

and

have been extended to halides, polyketones, polyesters, polycarbonates and polyamides, etc. the yields and demands of the products are moderate (10000-100000 tons). The carbonylation of

and

dimethyl ether to methyl acetate is also a route of industrial value. Ethanol can be obtained after hydrolysis. Methyl methacrylate (MMA) can also be extended from the carbonyl synthesis process. The project uses syngas and ethylene as raw materials to prepare MMA through hydroformylation, aldol condensation, and oxidative esterification. Now, many carbonyl synthesis projects have a certain foundation, with a scale of tens of thousands of tons to hundreds of thousands of tons, and its investment is only several hundred million yuan or more than one billion yuan It's totally affordable.

and

many coal chemical enterprises can add carbonyl synthesis side lines to form organic chemical products or new chemical material series. Although the output of tens of thousands of tons of products is not large, the added value of fine chemical products is high, and has a bright future. Some small ammonia and methanol enterprises can go to fine chemical industry with a little modification of carbonyl synthesis.
