Industrialization Progress in Cellulosic Fuel-ethanol Around the World

Vigorously promoting the industrialization of cellulosic fuel-ethanol could help alleviate the energy crisis and environmental pollution from fossil energy combustion in a long time. In this paper, the recent industrialization progress of cellulosic ethanol in six countries(China, USA, Canada, Sweden, Japan, Spain and Brazil) was mainly introduced, and raw cellulosic materials and technologies used in various demonstration and commercial plants were discussed. Finally, it was proposed that cellulosic fuel-ethanol could be commercialized only if several bottlenecks existing in sugar and syngas platforms were broken out.
