摘要
主要介绍了催化加氢、催化裂解、乳化、催化酯化、分子蒸馏这5种生物油精制方法。由于生物油精制技术都存在各自的问题,如:催化裂解具有设备简单、成本低等优点,但其催化剂容易结焦失活;乳化操作简单,但成本和耗能较多;催化酯化是一种较好的改性方法,但是改性后油的品质不高。这些都使生物油精制技术难以实现工业化。提出了一种在CO/H2O体系中精制生物油的新方法。
The study mainly introduces five kinds of bio-oil refining methods--hydrogenation, catalytic pyrolysis, emulsion, catalytic esterification and molecular distillation. Bio-oil refining technologies have their respective problems. For example, catalytic pyrolysis has advantages of simple equipment and low cost but catalyst is easily coked and deactivation; emulsion has simple operation but high cost and more energy consumption ; catalytic esterification is a good modification methods but the quality of oil is not high after modification. All these bio-oil refining technologies are hard to realize industrialization. Finally, a new method of bio-oil refining in the CO/H2O systems was also introduced.
