摘要:

论述了通过预处理褐煤提高焦油收率和品质的方案,并对比几种预处理方案的优缺点,热预处理和溶剂溶胀预处理易实现工业化;介绍了离子液体预处理研究进展,该法可显著增加热解焦油收率和轻质焦油收率。

Abstract:

The schemes of improving tar yield and quality by lignite pre-treatment are discussed.The advantages and disadvantages of different pre-treatment schemes are compared.Thermal pre-treatment and solvent swelling pre-treatment are easily to be industrialized.The development of ionic liquid pre-treatment is introduced.With this method,the pyrolysis tar yield and light tar yield can be remarkably increased.
