项目摘要

The requested CRD grant will support a research collaboration between Dr. Pedram Fatehi of Lakehead University and Dr. Michael Paleologou of FPInnovations. The team will make extensive use of kraft lignin samples produced at FPInnovations' lignin pilot plant in Pointe Claire, QC, FPInnovations' lignin demonstration plant in Thunder Bay, ON and at West Fraser's commercial lignin plant in Hinton, AB, as the raw materials of this research program. Recently, FPInnovations developed the LignoForce process for the production of high-quality kraft lignin from the black liquor of kraft pulping process. This process is now commercialized at West Fraser's Hinton mill in Alberta. The commercialization of kraft lignin facilitated the production of value-added products from kraft lignin. In phase I of this research collaboration, kraft lignin was successfully converted to flocculants and dispersants and two processes were developed for their production. To produce inexpensive and effective kraft lignin-based flocculants/dispersants with the desired characteristics for the mining and pulp & paper industries, the protocols for producing them should be further adjusted/revisited. In this research project (phase II), different alternatives will be explored to produce flocculants/dispersants from kraft lignin that are compatible with the technologies that the research group has already developed in phase I. FPInnovations will benefit from this research program by obtaining detailed data, techniques and technologies for the commercialization of kraft lignin-based products. The production of value-added lignin products from kraft lignin is crucial in the development of the kraft-based biorefinery, which will diversify the revenues of kraft pulp mills and eventually secure more jobs.

请求的CRD赠款将支持湖首大学的Pedram Fatehi博士和FPInnovations的Michael Paleologou博士之间的研究合作。该团队将广泛使用位于加拿大魁北克省Pointe Claire的FPInnovations木质素中试工厂、位于安大略省雷霆湾的FPInnovations木质素示范工厂和位于AB省欣顿的West Fraser商业木质素工厂生产的硫酸盐木质素样品作为本研究计划的原材料。最近，FPInnovations开发了LessandForce工艺，用于从硫酸盐法制浆过程的黑液中生产高质量的硫酸盐木质素。这一工艺现已在阿尔伯塔的西弗雷泽欣顿工厂商业化。硫酸盐木质素的商业化促进了从硫酸盐木质素生产增值产品。在该研究合作的第一阶段，硫酸盐木质素成功地转化为絮凝剂和分散剂，并开发了两种生产工艺。为了生产具有采矿和纸浆和造纸工业所需特性的廉价有效的硫酸盐木质素基絮凝剂/分散剂，应进一步调整/重新审视生产它们的方案。在该研究项目（第二阶段）中，将探索不同的替代方案，以从硫酸盐木质素中生产与研究小组在第一阶段已经开发的技术兼容的絮凝剂/分散剂。FPInnovations将通过获得用于牛皮纸木质素产品商业化的详细数据，技术和技术，从该研究计划中受益。从硫酸盐木质素中生产增值木质素产品对发展硫酸盐生物炼制至关重要，这将使硫酸盐纸浆米尔斯厂的收入多样化，并最终确保更多的就业机会。
