Abstract: The research progress in the pyrolysis and liquefaction of non-woody biomass was reviewed. The methods of liquefaction and the factors influencing liquefied products and their quality were introduced. The characterization methods,properties and the application of liquefied products were also addressed. Furthermore, several pyrolysis technologies which are popular in the world were introduced. Finally,it is indicated that the fundamental research work on the pyrolysis and liquefaction of non-woody biomass has practical significance.
