China's coal gasification technology won the first foreign invention patent

The on-line feeding technology for the gasification furnace gasification burner jointly developed by Yankuang Group and East China University of Technology has recently obtained the invention patents of the United States and South Africa. This is the first invention patent of China's coal chemical technology abroad.


According to the Yankuang Group's introduction, large-scale coal chemical equipment sets are complex, and coal gasification technology is the leading factor that determines the stability and continuity of the entire system. For a long time, patent technology in this area has been monopolized by foreign companies.


In order to change the situation of China's coal gasification technology controlled by people, from the “Eighth Five-Year Plan”, Yankuang Group and East China University of Science and Technology jointly formed a technology innovation and research alliance. After hard work, China built the first multi-nozzle opposed water coal in 2005. Compared with the imported single nozzle technology, the large-scale industrialization demonstration equipment for slurry gasification has improved the effective gas composition and carbon conversion rate by 2 to 3 percentage points, and all performance and technical indicators have reached the international advanced level.


At present, this new type of coal-water slurry gasification technology has broken the monopoly of foreign monopoly in the domestic market. It has been used by 23 companies, accounting for 60% of the domestic coal-water slurry gasification market share, and saving a patent fee of RMB 1 billion for Chinese enterprises. the above.


Yankuang Group believes that the on-line feeding technology of gasification burner gasifier has obtained invention patents in the United States and South Africa, further established the seat of the core technology of China's coal chemical industry independent intellectual property rights in the international market, and is China's coal chemical industry technology internationally. It won the right to speak.
