近年来,离子液体作为新型功能材料,在生物燃料制备中的应用逐渐增多。离子液体具有蒸汽压小、熔点低和液态温度范围宽等特点;在生物燃料制备中,具有不腐蚀设备、不污染环境、能够重复使用的优点。介绍了离子液体中纤维素的预处理、溶解和水解等;同时阐述了离子液体作为催化剂、溶剂及催化剂载体在生物柴油合成方面的应用研究进展,最后展望了离子液体在可再生生物燃料制备中的发展方向。
In recent years, ionic liquids as a new type of functional materials, the application of biofuels in the gradual increase. Ionic liquid has the characteristics of small vapor pressure, low melting point and wide range of liquid temperature. In the preparation of biofuel, it has the advantages of non-corrosive equipment, no pollution to the environment and reusability. In this paper, the pretreatment, dissolution and hydrolysis of cellulose in ionic liquid are introduced. The progress of application of ionic liquid as catalyst, solvent and catalyst carrier in the synthesis of biodiesel is also discussed. Finally, the application prospect of ionic liquid in the preparation of renewable biofuel The direction of development.
