The broader impact/ commercial potential of this project is the development of a catalytic process for the selective production of high value specialty chemicals from lignin. 70 million tons lignin waste, generated by paper and pulp industries and biorefineries annually. While lignin is a rich source of aromatic building block chemicals that can lessen our dependence on petroleum, its selective deconstruction into aromatic chemicals without affecting the value of carbohydrate is a big challenge. The proposed technology provides a unique solution to this challenge in which lignin constituent of wood biomass and municipal wood chips is selectively converted into two high value specialty phenolic compounds in one-step with the simultaneous production of reactive cellulose and xylose. The markets for the lignin derived phenols and their secondary products (isoeugenol, vanillin, dimethoxylphenol) are over $1.1 billion dollars per year of available market. Currently these chemicals are manufactured from high cost clove-oil and petroleum feedstock. If techno-economic analysis for large scale production is favorable, this one-step technology will greatly benefit the paper and pulp industries and biorefineries by generating value from lignin. This Small Business Innovation Research Phase I project will evaluate and establish the commercial feasibility and economic viability of this unique technology by demonstrating a more accurate economic analysis, process design and separation methods, and validating the products specifications for the target application. The current biorefinery processes make full use of the carbohydrate fractions of wood for the production of cellulosic ethanol and fermentable sugars. However, because of lack of effective technology for breaking the recalcitrant lignin, this fraction accounting for an average 25-30 wt% of the plant mass is largely underutilized. This one-step catalytic technology adds unique value by producing high value chemicals, increasing the overall carbon efficiency, while simultaneously delignifying biomass without the need for excess water.

该项目的更广泛的影响/商业潜力是开发从木质素选择性生产高价值特种化学物质的催化过程。每年由纸质和原始工业制成的木质素废物7000万吨木质素废物。木质素是可以减少我们对石油的依赖性的芳族基础化学物质的丰富来源，但其选择性解构为芳香化学物质而不会影响碳水化合物的价值是一个巨大的挑战。 提出的技术为这一挑战提供了一种独特的解决方案，在这种挑战中，木质生物量和市政木屑的木质素组成部分被选择性地转化为两种高价值的特种酚类化合物，同时生产反应性纤维素和木糖糖。木质素衍生的苯酚及其二级产品（Isoeugenol，香草素，二甲氧基苯酚）的市场每年可用的市场的11亿美元以上。目前，这些化学物质是由高成本的丁香油和石油原料生产的。如果针对大规模生产的技术经济分析有利，则该一步技术将通过产生木质素的价值来使纸张，纸浆工业和生物精炼厂受益匪浅。这个小型企业创新研究阶段I项目将通过展示更准确的经济分析，过程设计和分离方法，并验证目标应用程序的产品规格，从而评估和确定该独特技术的商业可行性和经济可行性。当前的生物填充过程充分利用木材的碳水化合物分数用于生产纤维素乙醇和可发酵糖。但是，由于缺乏打破顽固木质蛋白的有效技术，因此占植物质量的平均25-30 wt％的部分很大程度上不足。这项一步催化技术通过产生高价值化学物质，提高整体碳效率，同时在不需要过量水的情况下同时划定生物量，从而增加了独特的价值。
