In recent years, the province has made significant progress in research and development in the field of coal chemical industry and successively formed a number of new technologies and new processes with independent intellectual property rights. However, these high and new technologies have all drifted away. The Shanxi Coal Chemistry Institute of the Chinese Academy of Sciences has obtained the national invention patent of the ash fusion fluidized bed pulverized coal gasification process and device and the national utility model patent of the ash fusion fluidized bed pulverized coal gasification device. This technology makes full use of pulverized coal, has high gasification intensity, high carbon conversion rate, and large single-furnace production capacity. At the same time, the pollution environment is small, investment is low, and domestic technology is not subject to foreign technology constraints. This patented technology fills the gap in clean coal gasification technology in China. However, the earliest company to accept this technology was a company in Shaanxi. In October 2001, China's first ash fusion coal gasification demonstration plant was completed and put into operation at Shaanxi Chenghua Company.
In the world, only the Second Design Institute of Chemical Industry of Shanxi Province possesses advanced technologies for the production of methanol from coke oven gas with independent intellectual property rights. This technology can flexibly adjust the demand for self-use gas and methanol production gas in the coke oven and fundamentally solve the environmental pollution caused by coke oven gas venting. According to the analysis, the cost per ton of methanol is 200 yuan lower than the average cost of domestic coal-to-methanol, and the investment profit rate is 24%. However, in 2004, China’s first production facility for the production of methanol from coke oven gas was not the coke oven gas province in Shanxi Province. Instead, it was commissioned by the Coking and Gas Supply Company in Qujing, Yunnan Province. The second set was Jianou (Hebei) Coking Methanol Power Generation Project.
There are SJ-96 coking technology, calcium carbide furnace flue gas treatment technology, phenylhydrazine processing and extraction of key technologies, all in recent years have venture, but are outside the province.
According to the analysis of relevant persons, there are four reasons for Shanxi's phenomenon of blooming in the high-tech province of coal chemical industry. First, the level of local economy and the investment environment are not satisfactory; the second is related to the concept of investors, and the patentee considers it good. The patents can only be assured when they are handed over to high-quality investors. Third, the financing channels are poor, and the development and application of patented technologies are highly risky. Fourth, the government's support is insufficient.
Coal chemical technology is the leading Shanxi province in China. However, a group of high-tech coal chemical companies with independent intellectual property rights developed by the province have been repeatedly neglected. The phenomenon of “flower blooming†in Shanxi and “falling fruit†outside the province has occurred.
