The new technology is the key to coal from black to green - new technology

, coal - the chemical industry

China is a coal as the main one Energy Countries. View from the nature of coal, the traditional understanding of the people that coal itself contains more harmful compounds, in the process of transformation and use of emissions of many harmful substances will be higher than Oil , Natural gas It is not that "clean." Thus, according to the characteristics of coal, in order to bring coal from the dark green, must rely on technology to be realized.

From the international situation, the United States use of coal each year 10 million tons, 90% for power generation, Europe, South Africa, India and other countries and regions, but also use a lot of coal. Therefore, the new technology of coal use in the international arena is a topic of concern. Some experts believe that in the post-oil era, renewable energy, new energy use is undoubtedly an important way, therefore, reserves of coal as an abundant, readily available, Economy Of good primary energy, it is possible in the future for a long period of time will play an important role.

Present, China has a world-class coal mining and processing technology, but the application of these technologies is still an imbalance; recent years, the introduction of a number of advanced coal power generation technology, but the most advanced technology and a certain gap ; in the coal-oil technology, we have the world's leading large-scale direct liquefaction technology, and indirect liquefaction technologies are mature to industrial development; domestic large-scale advanced coal gasification technology has been applied to achieve industrialization and technology gap between advanced narrow.

Coal use to achieve change from the dark green, watching the process from the use of coal can be divided into three kinds of technology. First, coal mining, processing, mining and processing sectors to achieve cleaner, that coal combustion and conversion of pre-purification; Second, in the process of combustion and high conversion efficiency and reduce emissions of pollutants; third is the implementation of emissions after combustion or conversion purification and recycling of waste materials, such as proper handling and comprehensive utilization of ash. In addition, energy use on the end of coal into a clean energy, coal in the terminal used to achieve high efficiency of use and clean.

The past years, many small and medium sized power plants, inefficient, coal consumption per kilowatt-hour electricity supply to more than 400 grams of coal equivalent, if the use of new coal-fired power generation technologies, coal consumption for power supply units can be reduced to 300 grams of the following , energy saving effect is very impressive. Therefore, we must rely on technological innovation, on the continuous improvement of technical level and perfect to achieve this goal. These technological advances were reflected in the new technology, new materials, new equipment and new technology systems.

The development of clean coal technology is a real issue, but also a future problem. Therefore, only play the clean use of coal science and technology, support and guide to the economic development of our country means more savings and to Environmental protection The direction of change. All levels of government and society should be concerned about the energy technology innovation, increase investment in clean coal technology, focusing on the development of clean and efficient coal-fired power generation technology, the development of coal oil, natural gas, clean coal conversion technologies, the major focus of the project should be included in the national "12 5" science and technology planning, or planning, organizing domestic superior forces, increase the intensity of innovation, so that more coal in the use of green in the dark.
