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热解试验工艺（250 kg/h），用于再生木材废物（刨花板、胶合板、定向结构刨花板、层压木材等）的净化。并进行升级，同时遵守减少温室气体排放和空气污染物的监管标准。在这些废弃物中，木材通常含有富氮的热固性树脂（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，以促进热解气体的最佳燃烧，并集成一个新的后处理装置，以捕获残余气体污染物。该项目的第二阶段是为CarbonFX中试装置提供新型生物炭活化模块。该模块的好处是双重的：i）它将是一个进一步的处理，完全回收所有类型的残留污染物;和（ii）它将使生物炭转化为具有高工业潜力的活性炭。该项目还将促进从热解和活化系统中回收二氧化碳（CO2），并将水蒸气用作活化剂。该系统的能源自给性和木材废料的零或负成本将有利于拟议的综合工艺的经济可行性和环保性能。

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.
