摘要
贵州煤的灰分限制了它在煤质活性炭生产上的广泛利用,寻找一种廉价的除灰技术就成其发展的重要环节。本文研究了以物理和化学的除灰方法对贵州高灰分的煤进行除灰,可使灰分含量从12.05%下降至4.25%,可以满足生产中、高档活性炭的工艺要求。
The coal Guizhou has very high miner, so this has restricted the.its extensive use that it produces in coal quality activated carbon. It is very important for us to seek a kind of low- priced technology that demineralize for coal. This article is studied with physical and chemical method that reduces the mineral in coal. this kind of effective methodcan makedemineralize for coal from 12.05 % to 4.25 %. those coal can satisfy production the requirement of high grade activatedcarbon.
