"Eleventh Five-Year Plan" is a period of rapid development of China's coal chemical industry. According to statistics from relevant state departments, by the end of 2009, the total amount of coal-to-oil had exceeded 40 million tons, the total production capacity of coal-to-olefins was 20 million tons, and the amount of coal-based natural gas reached 25 billion cubic meters. The total investment of these projects exceeded. 1 trillion yuan. According to the reporter's understanding, the development of coal chemical industry shows a huge radiation effect, which provides a huge space for the development of related industries.
Coal is the basic raw material for the coal chemical industry, and the amount of coal used in coal chemical industry is huge. Taking coal-based oil as an example, 4 to 5 tons of coal are required for each ton of coal-based oil. Therefore, the development of the coal chemical industry has led to a substantial increase in the demand for the coal industry. The national coal output this year is expected to reach 3.2 billion tons, an increase of more than 50% from 2005. The more important gain is that the coal used in modern coal chemical industry is mostly low-heat coal, lignite, and “three high†(high sulfur, high ash, high ash melting point) inferior coal, making these previously unattractive resources fully efficient. Utilization has greatly optimized the structure of the coal industry.
Coal chemical industry is a technology-intensive industry, and the rapid development of coal chemical industry has greatly promoted the development of related technologies. So far, China has developed a number of coal gasification technologies such as ash fusion coal gasification technology, multi-nozzle opposed gasification technology, and multi-component slurry gasification technology, and independently developed a fluidized bed methanol to propylene technology. Coal indirect liquefaction technology, coke oven gas to methanol and so on. The rapid development of technologies such as coal-to-oil, coal-to-methanol, coal-to-acetic acid, and methanol-to-olefin technology has made China the most internationally-funded coal chemical technology company with the highest level of technology.
Coal chemical projects are large projects and their demand for equipment is also very large. During the "11th Five-Year Plan" period, coal chemical equipment industry has achieved great development. According to Yan Yongbin, chief engineer of the China Machinery Industry Federation, the localization rate of complete sets of coal chemical equipment in China has reached 90%. “In addition to coal-to-oil, coal-to-olefins equipment, other coal chemical equipment has been basically domesticated.†For example, the 1.2 million tons of piston thrust reciprocating compressor and coal chemical coal water slurry required for large-scale coal chemical industry. High and low pressure diaphragm pumps. China's self-developed methanol synthesis reactor has reached a production capacity of 300,000 tons per year, and it has the technical foundation for the construction of a 1.8 million tons/year ultra-large methanol production plant.
At the same time, the development of coal chemical industry also stimulated the progress of corresponding environmental protection technologies. A large number of coal chemical desulphurization technologies including low-temperature methanol washing have come out one after another. The “Fengxi Haichuan Catalytic Oxidation†sour gas treatment process successfully solved the problem of low-temperature, low-concentration acid gas treatment in the coal chemical industry. In the coal chemical wastewater treatment technology, membrane bioreactors, wet oxidation, plasma treatment, photocatalysis and electrochemical oxidation are also in the ascendant.
