摘要
我国非炼焦煤中的不粘煤、弱粘煤分别的占煤炭总储量的11.80%和3.90%。这两种煤具有低灰、低硫、高挥发分、高发热量、燃点低、反应性好的特点。除极少数可用作炼焦配煤外,目前大多数用作动力煤。本文就这些煤种提出了几个加工利用方案,旨在提高这些煤的应用价值。
In the non--coking coal of the country, about 11.8% and3.90% of the coal reserves are non--coking coal and weakly-coking coal.Both them has lower ash and sulfur content,higher volatile matter and ca-lorific value, lower ignition temperature and higher reactivity. Most ofthese coals have been used as a power fuel so far.This paper offers propo-sals for these comprehensive utilization, such as coking a blocky coke,. hotpressing a formed coke and making activated carbon or carbon molecular si-eve.
