Coal gasification technology development appears new chaos

In an interview and investigation conducted recently, the reporter discovered that as the world's largest coal gasification market in China, the development and application of coal gasification technology has presented many new chaos such as the concept of speculation, the imitation of replicas, and the lack of industrialization demonstration. In this regard, industry experts suggest that the development and application of China's coal gasification technology must focus on original innovation and standardize competition; we must also be vigilant that China once again becomes a testing ground for foreign coal gasification technologies.

It is understood that coal gasification technology is one of the key technologies for the clean and efficient utilization of coal, and it is also the leading technology of coal chemical industry. Up to now, China has become the world's largest coal gasification market for five consecutive years, and many domestic and international coal gasification technologies have shown remarkable power to seize the market. However, there are many new chaos in the process of popularization and application of coal gasification technology in China.

First of all, the concept of hype is more. It is understood that the concept of coal gasification technologies currently being promoted in China is many, such as complex, compact, and non-catalytic fluidization technologies. In this regard, Yu Guangsuo, director of the Institute of Clean Coal Technology at East China University of Science and Technology, said that if the coal gasification technology is divided into fixed, fluidized, and entrained beds, the technology of any hype concept still falls into these three categories. Change it. In addition, many coal gasification technologies use an unequal platform contrast method to raise their own and mislead users in terms of oxygen consumption, cold gas efficiency, and carbon conversion rate. In this regard, Wang Yang, a researcher at the Shanxi Coal Chemical Institute, said that the advantages and disadvantages of the coal gasification technology are linked together, and the advantages and weaknesses cannot be highlighted. Tang Hongqing, a senior engineer of China National Synthetic Oil Engineering Co., Ltd., also believes that the comparison of coal gasification technology indicators is a variable, which is related to operating temperature, coal types, etc., and is difficult to compare statically.

Second, there are many imitations and fewer independent innovations. At present, the development of domestic coal gasification technology is very popular, and universities, companies, research institutes, and design institutes go hand in hand. The research and development of U.S. coal gasification technology is led and coordinated by the U.S. Department of Energy. In this regard, the industry believes that the domestic long go hand in hand can cause low levels of repeated research and waste of resources. At the same time, a coal chemical expert who did not want to be named told reporters that in recent years, the development of coal gasification technology has been rapid, but it is not easy to invent a completely original original innovation process. Some domestic technical personnel created patents with “independent intellectual property rights” through small changes and small movements. Most of them did not have outstanding advantages and characteristics, and their practical significance was not significant.

Again, there are many technologies that have been promoted without industrial demonstration. At present, some overseas gasification technologies that have not been industrialized are also intended to be promoted in China. According to Tang Hongqing, there is a technology that belongs to the fluidized bed gasification. In the United States, only a pilot plant with a daily processing capacity of 50 tons of coal is built. It also faces rigorous ash disposal and other engineering problems. The waste pan process is only applicable to electricity generation. Suitable for chemical industry, companies should choose carefully.
