摘要
广西是我国亚热带面积最大的省区,有丰富的生物质资源,包括甘蔗、木薯、桉树、更新香蕉林等数量巨大的可再生生物质。其中甘蔗渣的数量在每年千万吨左右,质地干净,储存集中,便于开发利用。广西科学院一直在从事甘蔗渣分离炼制的研究,目标是采用无污染、无公害的方法把三种成分(纤维素、半纤维素、木质素)分离开,各尽其用。本研究探讨利用蔗渣木质素纺丝,并进一步制备碳纤维的可能性。木质素在蔗渣中约占22%左右,从蔗渣分离出的木质素的分子量高峰在15777D,玻璃点在148°C,适合于纺丝。木质素薄膜有良好的液体分散性,木质素纤维有很强的疏水性,预计在环保、化工等领域有重要应用。木质素纤维经过预处理、碳化、石墨化、表面处理后可转化为碳纤维,强度适中,成本低,预计在汽车等民用工业产品中有广泛用途。
In this study we explore the possibility preparing lignin fiber and lignin carbon fiber using bagasse via electrospinning. Lignin is one of the most abundant organic products on the Earth. Each year over 150 billion tons of lignin are renewably produced through plant photosynthesis reactions. However, lignin is a toxic by-product in pulp industry and cellulose-ethanol industry, which are discarded in the form of "black liquor", one of the main pollution sources for the inland water body. In recent years we made great efforts to separate the three main components(cellulose, semi-cellulose, and lignin) via green chemistry approach without pollution. Currently our targets are the full utilizations of the three components with high economic benefits. Among the three components in biomass the lignin is the most difficult one that cannot be used for useful products with high economic value. In the past two decades researchers from US and Sweden found that the lignin is a good raw material for carbon fiber with very low production cost.
