项目摘要
Lignocellulosic biomass from agricultural waste and non-edible plants represents an abundant, inexpensive, and renewable source of carbon for the production of bio-based fuels, chemicals, and polymers. To be truly sustainable, new conversion processes that favor the use of green solvents, non-precious metal catalysts, and offer optimal biomass utilization need to be explored. The research objective of this project is to investigate the deconstruction of lignin, an underutilized biopolymer which accounts for up to 30% of lignocellulosic biomass, and its conversion to high value-added bio-based phenolic precursors for the industrial production of drugs, cosmetics, flavoring agents, and epoxy resins. The process combines the depolymerization of lignin in supercritical solvents and the catalytic upgrading of the resulting fragments to desired bio-based products.The project will explore new processes to convert lignin, an industrial waste product that is currently burnt as low value boiler fuel, to high value-added chemicals of industrial significance. Specifically, the deconstruction and fractionation of industrial lignin in flow reactors using supercritical solvent mixtures will be studied in order to understand the involved mechanisms and identify conditions that favor high selectivity, thus benefiting the economics of the conversion process and the environment by reducing waste. High value building blocks such as p-coumaric acid and ferulic acid will be recovered while fractions with lower value monomers and oligomers will be further converted over nanostructured catalysts to bio-based phenolic platform chemicals. The outreach program primarily targets grades 7-12 high school teachers with the objective of generating excitement and interest in pursuing careers in STEM fields among their students.
来自农业废弃物和非食用植物的木质纤维生物质是一种丰富、廉价和可再生的碳源,可用于生产生物燃料、化学品和聚合物。为了真正可持续,需要探索有利于使用绿色溶剂、非贵金属催化剂并提供最佳生物质利用的新转化工艺。本项目的研究目标是研究木质素的分解及其转化为高附加值的生物酚类前体,用于药品、化妆品、调味剂和环氧树脂的工业生产。木质素是一种未得到充分利用的生物聚合物,占木质纤维生物质的30%。该过程结合了木质素在超临界溶剂中的解聚和所产生的碎片的催化升级为所需的生物基产品。该项目将探索新的工艺,将目前作为低价值锅炉燃料燃烧的工业废品木质素转化为具有工业意义的高附加值化学品。具体地说,将研究使用超临界混合溶剂的流动反应器中工业木质素的分解和分馏,以了解相关机理并确定有利于高选择性的条件,从而减少废物,从而有利于转化过程和环境的经济性。高价值的积木,如p-香豆酸和阿魏酸将被回收,而价值较低的单体和低聚物的馏分将在纳米催化剂上进一步转化为生物酚类平台化学品。该外展计划主要面向7-12年级的高中教师,目的是激发学生在STEM领域追求职业生涯的兴奋和兴趣。
