1.煤炭液化开采据报道,美国西弗吉尼亚大学研究人员正在研究一种用泵抽出煤浆而不需要从地层挖掘的新方法.这种方法可以回收不易开采的薄煤层和很深的煤层.据称,用泵抽煤的最大难题是要研究出一种能在地下把煤转换为液体或煤浆的经济方法.这种地下液化煤的基本概念是往煤层打钻孔,加进某些部分能溶解煤的溶剂,然后用泵把煤浆抽出.该大学研究人员试验过三十种溶剂,这
1. Coal Liquefaction Mining It is reported that researchers at the University of West Virginia in the United States are studying a new method of pumping out coal slurry without excavating from the formation, which can recover thin seam and deep seam that are not easy to mine. Said the biggest challenge pumping with coal was to develop an economical way to convert coal into liquids or coal slurries underground.The basic concept of underground liquefied coal was to drill holes into the coal seam and add some parts Can dissolve the coal solvent, and then pump out the coal slurry.This university researchers tested thirty kinds of solvents, which
