Shaanxi comprehensive self-energy advantages to develop coal chemical industry
Shaanxi's development of modern coal chemical industry has the advantages of resources, technology, and policies, such as 170 billion tons of proven coal reserves and 385 billion tons of long-term reserves, ranking third in the country. At the same time, Shaanxi Chemical Research Institute and many colleges and universities have strong scientific research strength and have achieved a number of scientific research achievements that have significant impact at home and abroad, such as the new generation of methanol to olefins (DMTO-II), coal-based oil, and so on. The industrial bodies of the nine major coal chemical industrial parks such as Fugu, Yushen and Yiheng are basically determined. However, the coal conversion rate in Shaanxi is still low. In 2010, the output of raw coal was 361 million tons, of which 230 million tons were exported to other provinces, and only 13.35 million tons of coal was used in the province. In addition to 1,4-butanediol, most of the existing coal chemical products are primary products and the development of fine chemicals is slow. The Shaanxi Provincial Decision Advisory Committee believes that in the five major industrial chains, coal-based olefins should rely on the DMTO-II technology owned by Shaanxi, and be further processed along the methanol-to-olefins (ethylene, propylene, and butylene) and their downstream processes. Focus on the development of engineering plastics such as polyethylene, polypropylene, and polystyrene, as well as acetic acid, acetic anhydride, oxalic acid, polyether polyols, vinyl acetate, acrylic acid, and esters, butanol, dimethyl phthalate, and oxalic acid. Octyl ester, dimethyl amide and other chemical products. The coal-to-aromatics industry can take two routes, one directly from methanol. China Huadian Group's 10,000-ton coal-based methanol to aromatics demonstration unit in Yulin was started in March last year, and will expand to a million-ton capacity after success. The second is the separation and preparation of coal tar. Shaanxi coking and blue carbon by-products are rich in tar, and can be extracted from terephthalic acid, dimethyl terephthalate, bisphenol A, aniline and other downstream products by extracting aromatics as a chemical raw material. The coal-to-ethylene glycol must vigorously develop downstream processing products, and at the same time promote the extension of ethylene glycol and aromatic hydrocarbon chains to engineering plastics and polyesters. At present, Shaanxi Coal Chemical Group plans to implement a 200,000-ton/year coal-to-ethylene glycol project. The coal-based fine chemical industry chain is more diversified. It can be extended to downstream products such as acetic anhydride, vinyl acetate, 1,4-butanediol, methanol protein, formaldehyde, polyoxymethylene, urea formaldehyde resin, EVA resin, dimethyl carbonate, polycarbonate, high-grade paint, etc. 4-butanediol extends to products such as tetrahydrofuran, spandex, and polyurethane; EVA extends to hot melt adhesives, resin modifiers, and shrink films. In addition, it can also be extended to downstream products such as melamine, methylamine, and dimethylformamide by synthesizing ammonia from coal. The development of coal-based oil production in Shaanxi has local characteristics: First, indirect liquefaction of coal to produce oil, that is, syngas uses high/low temperature Fischer-Tropsch process to produce fuel oil and high-end paraffin. Yankuang Group and Golden Nest Company adopt this technical route; It is the low-temperature hydrogenation of coal tar to produce oil, which can produce high-quality fuel oil, lubricating oil and other products. With regard to the five major industrial chains, Shaanxi is in the process of or is preparing to launch the implementation of the comprehensive utilization of coal in the Shenhua Dow's Yulin, the indirect liquefaction of the Yankuang Yulin coal, the extension of the comprehensive utilization of Jingbian coal's oil and gas resources, the production of aromatics from Huadian's Hengshou coal, and the clean energy of the coal from the Shaanxi coal chemical project. The eight major projects of olefins, Datang Yulin coal-to-electricity integration, China Coal Group's coal to olefins, and coal gasification and diversification coalification integration have a total investment of 371.4 billion yuan. After the completion of the project, the annual sales income will reach 257.9 billion yuan and profits will be realized. 515 billion yuan. Among them, four projects have been listed as national demonstration projects and one project has been listed as a demonstration project of the United Nations. The report suggests that the Shaanxi coal chemical industry should speed up technological innovation and seize the development of coal chemical industry. Leading enterprises such as Shaanxi Coal Chemical Co., Ltd. and Yanchang Petroleum Co., Ltd., organized scientific research institutions and universities to jointly participate in methanol carbonylation synthesis of dimethyl carbonate, acetic anhydride, acetic acid, coal water slurry additives, and methanol/carbon four/carbon five coupling reaction to make olefins. Catalytic conversion of methanol, production of aromatic catalysts, medium-low temperature coal tar upgrading and comprehensive utilization, long flame coal catalytic pyrolysis to improve the coal tar yield and other technologies joint research, and strive to come up with a number of scientific and technological innovation. During the “Twelfth Five-Year Plan†period, Shaanxi will focus on building a high-end, high-quality, high-tech industrial structure and vigorously develop a modern industrial industry with an on-site conversion rate of coal resources of over 50%. Modern coal chemical industry accounts for the total output value of petrochemical industry. Than to reach 45%.
