Mise à niveau de la technologie de pyrolyse CarbonFX pour la valorisation des déchets à base de bois et l'activation du biochar

该研发项目旨在改造现有的中试热解工艺(250公斤/小时)，以净化再造木材废料(刨花板、胶合板、OSB、层压板等)。并对其进行升级，同时遵守减少温室气体排放和空气污染物的监管标准。在这些废物中，木材通常含有富含氮的热固性树脂(氨基塑料树脂)和其他各种化学添加剂。该项目的第一阶段是采用“CarbonFX”快速热解技术来优化木材废弃物污染物的去除。技术改造将主要集中在燃烧室，以利于热解气体的最佳燃烧，并集成新的后处理装置来捕获残余气体污染物。该项目的第二阶段是为CarbonFX试验装置提供一种新型的生物炭活化模块。该模块的好处有两个：i)它将是对所有类型残留污染物的全面回收的进一步处理；以及(Ii)它将使生物炭转化为具有很高工业潜力的活性碳。该项目还将促进从热解和活化系统中回收二氧化碳(CO2)和用作激活剂的水蒸气。该系统的能源自给自足和木材废料的零成本或负成本将有利于拟议的集成工艺的经济可行性和环境性能。

This R & D project aims at adapting an existing pilot pyrolysis process (250 kg/h) for the decontamination ofreconstituted wood wastes (particleboard, plywood, OSB, laminated wood, etc.) and upgrade them, whilstcomplying with regulatory standards for reducing greenhouse gas emissions and air pollutants. In these wastes,wood generally contains nitrogen-rich thermosetting resins (aminoplast resins) and other various chemicaladditives. The first stage of this project is to adapt the "CarbonFX" fast pyrolysis technology to optimize theremoval of wood waste contaminants. The technological adaptation will mainly focus on the combustionchamber to favour an optimal combustion of the pyrolysis gases and integrate a new aftertreatment device tocapture the residual gas pollutants. The second stage of the project is to provide the CarbonFX pilot unit with anovel activation module of biochar. The benefits of this module are twofold: i) it will be a further treatment forfull recovery of all types of residual contaminants; and (ii) it will enable the transformation of biochar intoactivated carbon with high industrial potential. The project will also promote the recycling of carbon dioxide(CO2) from pyrolysis and activation systems and water vapor for use as activators. The energy self-sufficiencyof the system and the zero or negative cost of the wood waste will favour both economic viability andenvironmental performance of the proposed integrated process.
