Kraft Lignin is a co-product of Kraft pulp and paper mills. Domtar is commercially operating several Kraft mills where the lignin is extracted and combusted to generate low-value energy for the plant. The main objective of the proposed project is to investigate the conversion of lignin into high value products to enhance both economical and environmental benefits associated with the pulp and paper process. In this work, we are proposing to convert the lignin into a bio-oil, which can substitute phenol in phenol-formaldehyde resins used as wood adhesives for the manufacture of plywoods, as well as into a bio-char, which can be activated to produce activated carbon for water purification. At the Institute for Chemicals and Fuels from Alternative Resources (ICFAR) at Western University we have developed advanced biomass pyrolysis technologies that allow the processing of complex feedstocks which exhibit stickiness such as lignin. Moreover, we have perfected fractional condensation systems allowing the segregation of high quality fractions of bio-oil. The proposed research project will utilize these advanced ICFAR technologies to maximize the value of the Kraft lignin of Domtar by producing and testing the pyrolysis-derived value-added products.

牛皮纸木质素是牛皮纸纸浆和造纸厂米尔斯的副产品。Domtar正在商业化运营几家牛皮纸米尔斯厂，在那里提取木质素并燃烧，为工厂生产低价值能源。拟议项目的主要目标是研究木质素转化为高价值产品，以提高与纸浆和造纸工艺相关的经济和环境效益。在这项工作中，我们建议将木质素转化为生物油，它可以取代苯酚-甲醛树脂中的苯酚，用作木材粘合剂，用于制造木材，以及转化为生物炭，可以活化生产用于水净化的活性炭。 在西部大学的替代资源化学品和燃料研究所（ICFAR），我们开发了先进的生物质热解技术，可以处理具有粘性的复杂原料，如木质素。此外，我们还完善了分馏冷凝系统，可分离出高质量的生物油馏分。 拟议的研究项目将利用这些先进的ICFAR技术，通过生产和测试热解衍生的增值产品，最大限度地提高Domtar硫酸盐木质素的价值。
