Under the pressure of high oil prices and environmental protection, clean coal power generation and coal oil are becoming popular projects

At present, the technologies for obtaining clean fuel, synthetic oil, and chemical raw material gas through coal gasification are mature and applied abroad. In the near future, the construction boom of clean coal power generation and coal indirect liquefaction facilities is set off.
Coal produces syngas through a gasification plant and then feeds it into a combined cycle plant to generate electricity. It is called the coal gasification combined cycle power (IGCC) system; it produces syngas from coal gasification, and then refinances and synthesizes synthetic oil or other chemicals. It is called Coal Indirect Liquefaction Technology (CTL). Compared with the pulverized coal combustion device, the coal gasification combined cycle power generation system generates much less mercury, sulphur dioxide, NOx and other pollutants, and the efficiency is nearly twice that of the conventional coal-fired device, and greatly simplifies the carbon dioxide gas recovery device. . It is expected that coal power generation will reach 1,440 GW by 2030, and China, the United States, and India will have the fastest growth rates. Therefore, clean coal combustion power generation technology has broad prospects for development.
The IGCC and CTL projects are lively It is reported that Shell Natural Gas and American Power Generation Company provide coal gasification technology and is constructing a coal gasification power generation project for Australian Stanwell Company. The IGCC power generation project has a carbon dioxide recovery system. Notable are the WMPI company and a design team with world-leading technology that are developing a coal-to-oil plant that converts waste coal into electricity, heat, and ultra-clean liquid fuels, called the Clean Coal Power Generation (CCPI) program. . The plan was supported by the U.S. Department of Energy, and its members include Nexant, Shell Global Solutions, Wood, and Sasol. Nexant provides comprehensive services that organically combine Shell's coal gasification technology with Sasol's Fischer-Tropsch synthesis process. In addition, another demonstration unit that uses waste coal to generate electricity and produce clean fuel will be built in Pennsylvania, USA. The project will make full use of mining landfill waste to address the serious environmental issues faced by the US mining industry. The demonstration plant can convert 1.4 million tons/year of waste anthracite (40% ash coal) into 800 cubic meters/day of ultra-clean fuel and 131 megawatts of electricity.
Eastman Chemical is discussing gasification projects with several power companies and plans to jointly produce electricity and produce chemical raw materials. U.S. Synthetic Oil signed a contract with Australia's Linc Energy Co., Ltd. to jointly develop the CTL project in Queensland, Australia, and fully utilized Synthetic Oil's GTL technology and Linc Energy's underground coal gasification (UCG) experience. It is reported that the first phase of the industrialized application of the project will start next year, including the construction and operation of a 30 to 40 MW power generation unit; the second phase of the project will be completed in a few years, including a 17,000 bbl/day synthetic oil CTL plant and power generation. Device capacity expansion and so on.
China's CTL Project Enthusiasm High In August of this year, Headwaters, a leading developer of indirect CTL installations, signed two technology transfer contracts with relevant Chinese parties, and will build two sets of 30,000-tonne direct and indirect coal-fired systems in Inner Mongolia. Oil test device. At the same time, the United States has established indirect CTL installations in Arizona and North Dakota. The plant will produce approximately 10,000 barrels per day of ultra-clean diesel and other fuels, and use coal gasification combined-cycle power plants to generate electricity.
China is setting off an upsurge in the construction of coal-to-oil projects. According to relevant departments' estimates, including the proposed project, China's CTL production will reach at least 100 million tons/year by 2020. If this goal can be achieved, CTL will largely replace crude oil imports, accounting for one-fifth of China's oil demand by 550 million tons.
To fill the shortage of China's oil supply and the continued growth of imports of crude oil, fuels, and chemicals, it is necessary to build 10 to 15 sets of CTL devices for the Sasol technology. According to estimates by Southern Chemicals, China has 114 billion tons of coal reserves and 177 billion barrels of CTL oil. The premise of this conclusion is that assuming that most of China's coal reserves are converted into coal-based oil through 190 sets of CTL plants (80,000 barrels per day per set) in 50 years, most of China's coal is currently used for coal-fired power generation.
