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.
