洁净煤技术发展概况

煤炭是世界一次能源的重要组成部分,煤炭占世界能源的首位。但是煤炭又是不洁净的能源。它在为社会做出具大贡献的同时,在其开采、加工、储运和使用过程中,也产生一系列环境污染问题。必须提高煤炭的利用率,减少燃煤对大气的污染,发展洁净煤技术,以解决中国煤炭在开发利用中效率低和污染严重的问题。 Coal is the main primary energy in the world,but it is not clean energy.A series of environmental pollution problems during the mining、processing、transportation and utilization were created while it makes contribution to the society.Improving the efficiency of coal utilization,reducing the environmental pollution and developing Clean coal technology should be conducted for solving low efficiency utilization and serious pollutions in China
