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

卡夫木质素是卡夫纸浆和造纸厂的副产品。Domtar正在商业经营几家卡夫工厂，在那里木质素被提取并燃烧，为工厂产生低价值的能源。该项目的主要目的是研究木质素转化为高价值产品，以提高与纸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一种生物油，这种生物油可以替代酚醛树脂中的苯酚，用于制造胶合板的木材粘合剂，也可以转化为一种生物炭，这种生物炭可以被活化以生产用于水净化的活性炭。

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.
