降低木质纤维素燃料乙醇生产成本的分析

Analysis of Reducing Production Cost of Fuel Ethanol by Lignocellulose

自然界最丰富的可再生资源木质纤维素经过转化可以制取新能源——燃料乙醇,为解决当前的能源危机、粮食危机和环境危机提供了一条出路。由于成本方面限制的原因,纤维素乙醇目前并没有完全商业化。从原料、预处理、纤维素酶、发酵和蒸馏、生物精炼等方面分析了降低纤维素乙醇成本的可行性。

As the most aboundant renewable resource on the planet, lignocellulose could be used to produce the new energy-fuel ethanol, which provides a solution to the existing energy crisis, food crisis and environment crisis. However, lignocellulosic ethanol has not achieved complete commercialization yet due to high production cost. In this paper, the feasibility of the programs to reduce production cost of lignocellulosic ethanol from the aspects of raw materials, pretreatment, cellulase, fermentation, distillation and biorefining was analyzed.
