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.

所申请的 CRD 拨款将支持 Lakehead 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 FPInnovations 位于魁北克省 Pointe Claire 的木质素中试工厂、FPInnovations 位于安大略省 Thunder Bay 的木质素示范工厂以及 West Fraser 位于艾伯塔省 Hinton 的商业木质素工厂生产的牛皮纸木质素样品，作为这个研究计划。最近，FPInnovations 开发了 LignoForce 工艺，用于从牛皮纸制浆工艺的黑液中生产高品质牛皮纸木质素。该工艺现已在艾伯塔省 West Fraser 的 Hinton 工厂实现商业化。硫酸盐木质素的商业化促进了硫酸盐木质素增值产品的生产。在这项研究合作的第一阶段，牛皮纸木质素被成功转化为絮凝剂和分散剂，并开发了两种生产工艺。为了生产廉价且有效的硫酸盐木质素基絮凝剂/分散剂，并具有采矿和纸浆和造纸工业所需的特性，应进一步调整/重新审视其生产方案。在这个研究项目（第二阶段）中，将探索不同的替代方案，以牛皮纸木质素生产絮凝剂/分散剂，这些絮凝剂/分散剂与研究小组在第一阶段已经开发的技术兼容。FPInnovations 将通过获得详细数据从该研究项目中受益牛皮纸木质素产品商业化的技术和工艺。利用硫酸盐木质素生产增值木质素产品对于硫酸盐生物精炼厂的发展至关重要，这将使硫酸盐纸浆厂的收入多样化并最终确保更多就业机会。
