However, under China's current conditions of being rich in coal, poor in oil, and short of gas, coal will still occupy the dominant position in my country's energy structure for a long time. But it is also the main source of air pollution, and the environmental problems caused by it have attracted more and more intense attention from governments at all levels and the public. Therefore, using clean coal has become our inevitable choice.
Wang Yusuo, member of the National Committee of the Chinese People's Political Consultative Conference and chairman of the board of directors of ENN Group, said that coal-to-gas production is an important direction for the clean utilization of coal, especially for replacing scattered coal use that emits serious pollutants. This year he put forward a proposal to "Develop independent and innovative coal gasification technology to achieve clean utilization of coal." At present, my country has approved multiple coal-to-gas projects including Datang Chifeng in Inner Mongolia, Datang Fuxin in Liaoning, Huineng Ordos, and Kingho Xinjiang Yili.
However, since the start of the project demonstration in 2016, problems and controversies such as production fluctuations, low efficiency, environmental pollution, and high water consumption have emerged one after another. Wang Yusuo pointed out in the proposal that there are two basic facts that cannot be ignored. One is the current coal gasification technology. The initial research and development design was for the production of chemicals, such as synthetic ammonia, coal-to-methanol, etc., in gasification Try to avoid generating methane gas during the process. After being used to produce energy, such as coal-to-gas production, although the process has become increasingly mature through experiments, it cannot fundamentally change its basic characteristics of low energy conversion efficiency and high resource consumption. Second, these coal gasification technologies were all developed in early foreign countries. Environmental problems were not prominent at that time, so environmental protection requirements were not considered too much during research and development. As environmental pressure becomes increasingly prominent, the inherent shortcomings of these old technologies have gradually emerged.
Therefore, current research and development technology must study gasification technology for coal gas production. Current science and technology and environmental protection technology can fully support us in making this gasification technology more environmentally friendly. Wang Yusuo said in an interview with a reporter from China Business News.
Talking about a domestic coal-to-gas demonstration project, Wang Yusuo said that I think the demonstration project is just to demonstrate whether coal-to-gas can be realized. I now propose that it has reached the stage of demonstrating the scientific nature of our technology. ENN is currently working on a technology. Coke oven gas methanation technology has been industrialized. Underground gasification technology and catalytic gasification technology have been applied in Pingdingshan and Tangshan. Industrial demonstrations are about to begin. Hydrogenation gasification technology and supercritical water coal gasification technology are currently being developed. It is in pilot testing and is expected to basically reach industrialization by the year. This gasification technology is developed for different types of coal.
my country is the main market for the application of coal gasification technology. Relying on imported technology is not a long-term solution. It must be combined with the actual domestic situation and through independent innovative technology research and development to form a coal gasification technology that adapts to the characteristics of different domestic coal types and further establish the coal gasification technology. oriented technical standards system.
