木质纤维素生物质越来越被认为是一种碳中性资源，而不是一种有机固体废物。它可用于生产各种增值化学品和生物燃料，如生物油。然而，生物油的化学不稳定性、低热值、高腐蚀性和高粘度等不良性质极大地限制了生物油作为替代燃料的利用。因此，生物油应该升级。近年来，人们开发了一些新的方法，如电催化加氢、常压蒸馏和等离子体辅助催化，以在温和条件下提高生物油的质量。在这里，我们概述了在过去几年中获得的木质纤维素生物质的分子结构的新知识，并讨论了未来的挑战和机遇，进一步推进生物油的生产和升级从木质纤维素生物质。详细分析了可持续生物质资源回收系统的发展，以提高效率和最小化对环境的影响。此外，还对其环境影响和可持续性进行了评估。最后，确定了剩余的知识差距，并强调了未来的研究需求，可能导致大规模生产的生物燃料从木质纤维素生物质。
Lignocellulosic biomass is increasingly recognized as a carbon-neutral resource rather than an organic solid waste nowadays. It can be used for the production of various value-added chemicals and biofuels like bio-oil. However, the undesirable properties of bio-oil such as chemical instability, low heating value, high corrosivity, and high viscosity are greatly restricting the utilization of bio-oil as a drop-in fuel. As a consequence, bio-oil should be upgraded. Recently, several emerging methods, such as electrocatalytic hydrogenation, atmospheric distillation, and plasma-assisted catalysis, have been developed for improving the bio-oil quality under mild conditions. Here, we overview the new knowledge on the molecular structure of lignocellulosic biomass gained over the past years and discuss the future challenges and opportunities for further advances of the bio-oil production and upgrading from lignocellulosic biomass. The development of sustainable biomass resource recycle systems with improved efficiency and minimized environmental impacts is analyzed in details. Also, their environmental impacts and sustainability are evaluated. Lastly, the remaining knowledge gaps are identified, and the future research needs that may lead to massive production of biofuels from lignocellulosic biomass are highlighted.
