Reporter learned from Huadian Group on the 11th, by the Huadian Group and Tsinghua University jointly developed with China's independent intellectual property coal-derived aromatic technology come out. This technology to fill the international gap, will promote the clean and efficient use of coal, effectively alleviate the current shortage of crude oil in China. At the same time, the world's first 10,000-ton methanol aromatic plant test equipment is also built in Shaanxi Province. Aromatic is the bulk of organic chemical raw materials, are widely used in apparel fabrics, aerospace, transportation , mobile communications, etc. At present, China's annual consumption of more than 20 million tons. At present, more than 97% of aromatics comes from petroleum raw materials, and the current shortage of crude oil in our country also brings constraints to its development. In 2012, the self-sufficiency rate of aromatics in China was only 55.9%. It is imperative to develop coal-to-aromatics technology. Jin Yong, a member of the Chinese Academy of Engineering, told reporters that coal-based aromatics mainly go through three steps. After the coal is produced by clean coal gasification, syngas is generated and syngas is converted into methanol. Methanol is further transformed into aromatic hydrocarbons. At present, the first two steps have mature industrialization technologies both at home and abroad, but the industrialization technology of methanol to aromatics is still blank. "This technology fills the international void and opens up new ways of coal-based energy and chemical industry, which is of great significance for the substitution of China's petrochemical raw materials and grasping the new development opportunities of the world's energy and chemical industry," said Yun Cimin, general manager of Huadian Corporation. The world's first 10,000-ton methanol aromatic plant pilot plant has been built in Yulin, Shaanxi, and will be gradually industrialized.
