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.

加拿大拥有世界上第三丰富的森林资源，这是其主要的国内生产总值 **（国内总产值）。这也为加强加拿大的生物经济提供了一个机会，因为生物能源部门仍然有未开发的森林残留物利用途径。这些途径之一是将基于森林的木质纤维素生物质，确切地说，木质素转化为高价值的平台化学品。木质素被认为是地球上最丰富的可再生生物质之一。目前，大多数生物精炼厂都专注于将木质纤维素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物，仅使用木质纤维素的纤维素和半纤维素组分。然而，木质素是几种高价值平台 ** 化学品的丰富来源，只要以系统的方式对其进行加工。目前，EMO 3开发的独特臭氧处理技术 ** 已在多个领域得到应用，如生物甲烷化厂、污水处理厂、垃圾处理和卫生坑、冷却塔等。该公司寻求开发一种新型设备，以扩大其臭氧处理技术在生物精炼和生物基平台化学品生产中的应用。这项工作的目的是开发一种经济有效和生态友好的方法 ** 来处理和转化木质素为高价值的平台化学品。该方法使用基于臭氧的脉冲 ** 处理来定制木质素聚合物的解聚成各种商业上高价值的单体 ** 单元，例如阿魏酸、3-羟基肉桂酸和对香豆基/芥子基/松柏基，这可以显著 ** 促进加拿大生物基经济。
