项目摘要

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，莱克黑德大学生物修补研究所的Fatehi博士以及Fpinnovations的Daniel Beaudoin博士将调查用于在苯酚甲醛和环氧树脂中应用脱甲基化和去脱聚合的木质素衍生物的生产，以及多氨基氨基泡沫。目前，卡夫木质素和水解木质素是通过FpinNovations开发的木佛佛罗里达和TMP-BIO技术在加拿大商业前和商业规模生产的。但是，通过这些技术生产的木质素的使用在行业中受到限制。在这个拟议的合作项目中，将对基于水性的系统中产生脱甲基化和去聚合的木质素衍生物的机会进行基本评估。将检查各种创新的途径，以产生脱甲基化和去聚合的木质素衍生物，以在粘合剂，树脂和泡沫中使用，并且将详细评估与木材和TMP-BIO工艺最兼容的过程，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开会，以便可以对开发的技术进行调整并实际实施到现有技术中。新工艺将有助于FPINNOVATIONS在纸浆厂（例如西弗雷泽木材公司）中采用开发的技术，以将价值的木质素产品商业化。此外，该项目将使Fatehi博士能够调查与脱甲基化和去聚合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本原理。木质素衍生的化学物质的生产是建立木材基生物融资的途径，该途径将增加和多样化加拿大纸浆厂的收入。
