纤维素类生物质合成多元醇的研究进展

Research Progress on the Preparation of Polyhydric Alcohols from Cellulosic Materials

随着化石能源的日益耗竭,可再生的生物质能源成为最理想的替代能源。通过催化转化的方法将生物质转变为重要的工业原料是解决能源危机的有效手段。多元醇作为一种重要的工业原料,可以用来合成氢气、液体燃料和化学品。作为自然界最为丰富的生物质,纤维素可以通过催化转化的方法转变为多元醇。本文对纤维素类生物质合成多元醇的方法及研究进展进行了评述,提出了一步法水解/氢化和直接氢化法为纤维素类生物质合成多元醇的可能的发展方向。

As the increasing depletion of the fossil energy,the renewable biomass energy was becoming an ideal alternative.It was effective means of solving the energy crisis that the biomass was converted into important industrial raw materials via catalysis.Polyhydric alcohols,a kind of important industrial raw material,can be used for preparation of hydrogen,liquid fuel,and chemicals.Cellulose,which was the most abundant biomass in nature,can be converted into polyhydric alcohols via catalysis.The techniques and research progress of conversion of cellulosic materials into polyhydric alcohols were reviewed.The possible trend of preparation of polyhydric alcohols from cellulosic materials was forecasted.
