Biorefinery based on biomass resources is an important approach for the oil refining and petrochemical industry to achieve sustainable development.Two types of biorefinery suitable for China’s biomass resources are presented in this paper.With sorgo and cassava as raw material,an ethanol-biorefinery for the production of ethanol-gasoline and chemicals is explored,and with rape seed and cotton seed oil as raw material,a biodiesel-biorefinery for the production of biodiesel and chemicals is also explored.The associated problems and measures taken are discussed in the end.
