木质素如今市值超过1 300亿美元,是未来化学工业的主要可再生芳香族资源。木质素有望在2015年首次在酚醛树脂、表面活性剂、环氧树脂黏合剂或聚酯等工业应用中取代苯酚,成为主导。木质素占地球上所有非石化有机碳资源的30%。其供给量超过3 000亿t,并以每年200亿t的速度持续增长。木材中含有大量木质素,约占木材的20%~35%(质量分数)。同木材中的其他成 Lignin, with a market capitalization of more than $ 130 billion today, is the main renewable aromatic resource for the future chemical industry. Lignin is expected to lead for the first time in 2015, replacing phenols in industrial applications such as phenolic resins, surfactants, epoxy adhesives or polyesters. Lignin accounts for 30% of all non-petrochemical organic carbon resources on Earth. Its supply exceeds 300 billion tons and continues to grow at a rate of 20 billion tons per year. Wood contains large amounts of lignin, accounting for about 20% of wood 35% (mass fraction). Other wood in the same
