摘要
褐煤是一种高挥发份、高水份、高灰份、低热值、低灰熔点的煤炭,具有易自燃,不适合长期储存和长距离运输的特性,因此长期以来被视作劣质燃料,开发利用程度低。定量分析褐煤洁净化和煤化工装置的联产,提出尿素和天然气两种产品路线的技术经济方案,探索符合国情的褐煤综合利用途径。
Lignite is a kind of coal with the high volatile content,high moisture,high ash,low calorific value and low ash melting point,which yields the properties of spontaneously flammable,unsuited to long term storage and long range transport,and has long been regarded as a kind of the low-grade fuel of under-development and inadequate utilization.Based on quantitatively analyzing the co-generation of the clean coal technology of lignite and the coal chemical industry,put forward the techno-economic options to produce urea and natural gas and probe on the comprehensive utilization of lignite in conformity with the national conditions.
