The focus of the five-year program is to develop green adsorbent based gas treatment systems to remove problematic compounds and meet infrastructure/space constraints in remote/harsh environments. The underlying principle is green processing, where materials used are sustainably sourced, and energy/waste are minimized. The adsorbents will be derived from products of the thermochemical conversion of forestry and fishery residues. We have already demonstrated that the thermochemical conversion (fast and slow pyrolysis) of forestry residues produces not only a source of energy but also high value chemicals and materials. This work focuses on the biochar generated as a "by-product" in fast pyrolysis. The overall objective of this work is to develop adsorbents derived from biochar to treat gas streams, particularly in locations where the treatment options are limited due to location and/or infrastructure. The biochar will be sourced from sawmill residues, shellfish by-product, and combinations of these materials in order to maximize the different composition/functionalities these feedstocks bring to the biochar. The short term objectives are to; develop applications for bioadsorbents based on the surface properties that different residues/modifications bring to the biochars; develop methodology based on molecular modelling (MM) tools to "screen" target gas compounds affinity for adsorption thereby reducing the number and costs associated with experiments; develop mass transfer and kinetic models for scale up of fixed bed adsorbents; determine regeneration/sequestration capacity of char as a function of feedstock and application for long term re-use and disposal assessment; develop HQP who are technical experts in bioproduct development AND see the opportunities in "residues" and remote regions.  The proposed research will generate new knowledge with the strong potential to strengthen Canada's bioproduct base and increase the number of HQP trained as experts in the bioeconomy. These HQP will have skills ranging from fundamental research and modelling, product development, market challenges, policy development, and how infrastructure plays into product development. In short they will be able to transition to academic, government, or industry (potentially as an entrepreneur) from their graduate work.

该五年计划的重点是开发基于绿色吸附剂的气体处理系统，以去除有问题的化合物，并满足偏远/恶劣环境中的基础设施/空间限制。基本原则是绿色加工，使用的材料来源可持续，能源/废物最小化。吸附剂将从林业和渔业残留物的热化学转化产物中提取。我们已经证明，林业废弃物的热化学转化（快速和缓慢热解）不仅可以产生能源，还可以产生高价值的化学品和材料。这项工作的重点是作为“副产品”在快速热解过程中产生的生物炭。这项工作的总体目标是开发从生物炭中提取的吸附剂来处理气流，特别是在由于位置和/或基础设施而限制处理选择的地方。生物炭将来自锯木厂的残留物、贝类副产品，以及这些材料的组合，以最大限度地发挥这些原料给生物炭带来的不同成分/功能。短期目标是：根据不同残留物/改性给生物炭带来的表面特性，开发生物吸附剂的应用；开发基于分子建模（MM）工具的方法，以“筛选”目标气体化合物的吸附亲和力，从而减少与实验相关的次数和成本；建立固定床吸附剂的传质和动力学模型；确定炭的再生/固存能力，作为原料的功能和长期再利用和处置评估的应用；发展HQP，他们是生物产品开发的技术专家，并看到“残留物”和偏远地区的机会。拟议的研究将产生具有强大潜力的新知识，以加强加拿大的生物产品基础，并增加HQP作为生物经济专家的培训人数。这些HQP将具备基础研究和建模、产品开发、市场挑战、政策制定以及基础设施如何在产品开发中发挥作用等技能。简而言之，他们将能够从他们的研究生工作过渡到学术、政府或行业（可能作为企业家）。
