Pulsed-ozonolysis technology to enhance sustainable production of lignin-based platform chemicals

加拿大拥有世界上第三丰富的森林资源，为其主要的国内生产总值(GDP)做出了贡献。这也为加强加拿大的生物经济提供了机会，因为生物能源部门仍有尚未开发的**森林残渣利用路线。**此类路线之一是将森林木质纤维生物质，准确地说，木质素转化为高价值**平台化学品。木质素被认为是地球上最丰富的可再生生物质之一。目前，大多数生物炼油厂都专注于将木质纤维生物质转化为生物燃料，其中木质素被认为是生物燃料生产过程中的废物剩余，只使用木质纤维的纤维素和半纤维素成分。然而，木质素是几种高价值平台**化学品的丰富来源，只要它以系统的方式进行处理。目前，EMO3开发的独特臭氧处理技术**已在不同部门实施，如生物甲烷化工厂、废水处理**工厂、垃圾和卫生坑处理、冷却塔等。该公司寻求开发一种**新型设备，以扩展其臭氧处理技术，用于生物精炼和生产**生物平台化学品。这项工作的目标是开发一种具有成本效益和生态友好的方法**来处理木质木质素并将其转化为高价值的平台化学品。该方法使用基于臭氧的脉冲**处理，将木质素聚合物量身定做地解聚成各种商业高价值的单体**单元，如阿魏酸、3-羟基肉桂酸和对香豆基/香豆基/松柏基，这可能会显著**促进加拿大的生物经济。

Canada has the third richest forest resource in the world, which contributes to its major gross domestic product**(GDP). This also opens an opportunity to strengthen Canada's bio-based economy, as there are still unexploited**routes for forest residue utilization in the bioenergy sector.**One of such routes is to convert forest based lignocellulosic biomass, precisely, the lignin into high value**platform chemicals. Lignin is considered as one of the most abundant renewable biomass on the planet. At**present, most of the biorefineries are focused on converting lignocellulosic biomass into biofuel, where the**lignin is considered as a waste surplus in the process of biofuel production that uses only the cellulose and**hemicellulose components of the lignocellulose. However, lignin is a rich source of several high value platform**chemicals, provided it is processed in a systematic manner. At present, the unique ozone treatment technology**developed by EMO3 is implemented in diverse sectors, such as biomethanization plants, wastewater treatment**plants, treatment of garbage and sanitary pit, cooling towers, among others. The company seeks to develop a**novel equipment to expand its ozone treatment technology for applications in biorefinery and production of**bio-based platform chemicals. The objective of this work is to develop a cost effective and eco-friendly method**to treat and convert wood-based lignin into high value platform chemicals. The method uses ozone-based pulse**treatment for tailored depolymerization of lignin polymer into various commercially high value monomeric**units, such as ferulic acid, 3-hydroxycinnamic acid and p-Coumaryl/Sinapyl/Coniferyl that could significantly**boost the Canadian bio-based economy.
