Production of adhesives and activated carbon from BioChoice lignin via fast pyrolysis

硫酸盐木质素是硫酸盐纸浆和造纸厂的联合产品。Domtar正在商业化运营几家硫酸盐工厂，在那里提取并燃烧木质素，为工厂生产低价值的能源。拟议项目的主要目标是研究将木质素转化为高价值产品，以提高与制浆和造纸过程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，以取代苯酚-甲醛树脂中的苯酚，用作胶合板生产中的木材粘合剂，并转化为生物炭，可被活化以生产净水用活性碳。 在西方大学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，可以加工木质素等具有粘性的复杂原料。此外，我们还完善了分级冷凝系统，允许分离高质量的生物油分级。 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的硫酸盐木质素的价值。

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.
