In this collaborative project, Dr. Fatehi of the Biorefining Research Institute at Lakehead University, along with Dr. Daniel Beaudoin of FPInnovations, will investigate the production of demethylated and depolymerized lignin derivatives for application in phenol formaldehyde and epoxy resins, as well as poly urethane foams. Currently, kraft lignin and hydrolysis lignin are produced at pre-commercial and commercial scales in Canada via the LignoForce and TMP-Bio technologies that FPInnovations developed. However, the use of lignin produced via these technologies is limited in industry. In this proposed collaborative project, the opportunities for producing demethylated and depolymerized lignin derivatives in aqueous based systems will be fundamentally evaluated. Various innovative pathways will be examined to produce demethylated and depolymerized lignin derivatives for their use in adhesives, resins and foams, and the most compatible process with the LignoForce and TMP-Bio processes will be evaluated in detail for facilitating their adaptation and commercialization. Dr. Fatehi and FPInnovations' staff will collaborate closely and meet on a quarterly basis so that the developed technology can be adapted and practically implemented into the existing technologies. The new processes will assist FPInnovations in adopting the developed technologies in pulp mills (e.g., West Fraser Timber company) for commercializing the valorized lignin products. Additionally, this project will enable Dr. Fatehi to investigate the fundamentals associated with the application of demethylated and depolymerized lignin derivatives in adhesives, resins and foam applications. The production of lignin-derived chemicals is a pathway to establish wood based biorefinery, which will increase and diversify the revenues of pulp mills across Canada.

在这个合作项目中，湖首大学生物精炼研究所的 Fatehi 博士与 FPInnovations 的 Daniel Beaudoin 博士将研究用于苯酚甲醛和环氧树脂以及聚氨酯的去甲基化和解聚木质素衍生物的生产泡沫。目前，硫酸盐木质素和水解木质素在加拿大通过 FPInnovations 开发的 LignoForce 和 TMP-Bio 技术以预商业和商业规模生产。然而，通过这些技术生产的木质素在工业中的使用受到限制。在这个拟议的合作项目中，将从根本上评估在水基系统中生产脱甲基和解聚木质素衍生物的机会。将检查各种创新途径来生产用于粘合剂、树脂和泡沫的去甲基化和解聚木质素衍生物，并且将详细评估与 LignoForce 和 TMP-Bio 工艺最兼容的工艺，以促进其适应和商业化。 Fatehi 博士和 FPInnovations 的员工将密切合作并每季度举行一次会议，以便开发的技术能够适应并实际应用到现有技术中。新工艺将协助 FPInnovations 在纸浆厂（例如 West Fraser Timber 公司）采用已开发的技术，将增值木质素产品商业化。此外，该项目将使 Fatehi 博士能够研究与脱甲基和解聚木质素衍生物在粘合剂、树脂和泡沫应用中的应用相关的基础知识。木质素衍生化学品的生产是建立木材生物精炼厂的一条途径，这将增加加拿大各地纸浆厂的收入并使收入多样化。
