China's coal chemical industry basically depends on foreign technical support

The reporter learned from the just-concluded China (Taiyuan) International Coal and Energy New Industry Expo that the coal-rich provinces in China have a strong desire to develop coal chemical industry and are in contact with foreign energy giants who have mastered the clean coal core technology. This situation in which foreign technology controls China’s industries has caused concern among people of insight.
Due to China's coal-rich energy resources, Chinese companies are eager to develop coal chemical industry. However, at present these companies have introduced or are considering the introduction of foreign core technology, coal chemical equipment has presented a "national card" trend. At present, with the rapid development of China's coal chemical industry, foreign energy giants have been deeply involved in China's coal chemical industry. The South African Sasol Company, which has mastered coal indirect liquefaction and mature commercial technology, cooperates with Shenhua Group, China’s largest coal chemical company, and plans to build two coal indirect liquefaction plants in Ningxia and Shaanxi with an annual production capacity of 3 million tons of oil, equivalent to daily It can replace 80,000 barrels of oil. The Shell Company of China and China Shenhua Ningmei Coal Group signed a similar agreement in July this year and will use shell coal indirect liquefaction technology to study the feasibility of constructing a 70,000-barrel-per-day coal-to-oil plant. The Air Liquide Group of France cooperates with Shenhua Ning Coal and is building the world's first coal chemical project that uses polypropylene as raw material to produce polypropylene, with an investment of about 17 billion yuan. In February this year, Germany's Siemens Power Generation Group and Shenhua Ning Coal also signed an agreement for the production of alcohol ethers from coal. Prior to this, Lurgi, Texaco, General Motors and other coal chemical giants also exported technology to build a number of large-scale coal chemical projects in China.
At present, foreign energy giants have been deeply involved in and even control China's coal chemical industry with its core technologies. Considering that the coal-to-oil, coal-to-olefin and other coal chemical projects have huge investments and the technology is yet to be matured, the Chinese government decided to limit it to demonstration projects before 2010. Some companies are keen to introduce foreign and immature coal chemical technologies, knowing that the project is unlikely to be launched. The people of insight are therefore worried that China's coal chemical equipment presented this kind of "national card" trend, I am afraid that the development of coal chemical industry is endless.
The reporter noted that on September 17, Baotou Baotou Coal Chemical Company and the Dalian Institute of Chinese Academy of Sciences held a signing ceremony for a 1.8 million tonne/year DMTO technology transfer contract. This is China's first large-scale localization technology for coal chemical industry, and has a landmark significance for the development of China's coal chemical industry using domestic technology.

Chain stitch is a technique for sewing or embroiding a series of looped stitches, in purpose of forming a  chain-like pattern. Thus our chainstitch sewing machine can be simply considered as chain-like stitching machine for industrial sewing applications. Sewing is a very important process in the garment production process. Different sewing patterns are needed to meet different clothing requirements.
