Abstract:

Energy resources，especially the petroleum，become more and more limited，which push our society to develop new continuously renewable energy sources. In this paper，some possible substitute routes and their future in energy and petrochemicals replacing by biomass are described. It shows that the biomass resources can not only be the direct substitute of liquid fuels，such as fuel ethanol and bio-diesel，but also can be the indirect substitute of petroleum，such as basic bio-chemicals and functional polymers. Biochemical technology development will accelerate the progress of petrochemical industry，and make it more sustainable.
