浅谈褐煤的形成机制及开发加工利用

Superficial Discussion on Lignite Formational Mechanism, Exploitation, Processing and Application

我国北方地区褐煤储量很大,产地比较集中,辽宁的沈北地区也有一定储量,其中大部分是低灰、低硫煤。依据多年的地质勘查资料,对沈北地区含煤盆地的成生发展及褐煤形成机制进行了分析,认为我国东北部地区的褐煤盆地群属晚侏罗世—早白垩世期间的内陆—滨海相沉积,并呈现出明显的煤质分带。目前褐煤的用途仅用以燃料,若采用现代技术进行合理加工,不仅可以用于兴建坑口电站,还可以用于开发水煤浆、气化、液化、碳素制品、制取腐植酸、褐煤蜡等新产品领域。

There are abundant lignite resources concentrated in northern China, a certain amount of lignite in Shenbei area, Liaoning Province and most of them low ash and low sulfur lignite. Based on geological exploration data accumulated in many years, analyzed coal basin generation and development, as well as lignite formational mechanisms. Considered that the lignite basins in Northeast China belong to Late Jurassic-Early Cretaceous interior-littoral facies sedimentation and have presented distinct zoning of coal quality. At present, lignite is only used as fuel, if processed through modern technology with reason, can be used not only in pit- mouth power plant, but also in new domains of coal slurry development, gasification, liquefaction, carbon products, humic acid and montan wax manufacturing etc.
