R&D of Green and High Efficient Cellulosic Fuel Ethanol Process Combined with Value Added By-Products By Three Main Feedstock Components

As the biggest developing country, China needs fuel ethanol to meet its demands of the social and economy development. Basing on the “Mid-long term plan for renewable energy” established in 2007, the annual consumption of fuel ethanol will reach 10 million tons in 2020. Cellulosic ethanol, one of the most important second generation biofuel, gains more and more attentions for its substitution of the transportation liquid, lessen the air pollution by the vehicles and promote the rural area economy. In Guangzhou Institute of Energy Conversion, a green and high efficient Cellulosic fuel ethanol process combined with value added by-products by three main feedstock components is proposed. One ton ethanol can be produced with 5.68 t sugarcane bagasse, as well as 0.96 t CO2, 0.96 t Xylooligosaccharides and 1.59 t lignin. The lignin was used for the mushroom medium which can produce nutrient - rich Lentinula edodes successfully.
