Study on Biochar Drying and Pyrolysis Kinetics in a Laboratory and Application of the Data in Modelling Large Scale Industrial Biochar Plant

生物质是一种可再生的碳来源，可以转化为生物燃料或其他有价值的材料。**热解是一种相对简单、低成本的热化学技术，可以将生物质转化为生物油、生物炭和合成气。生物炭是一种高含碳量的材料，是在缺氧的气氛中加热生物质而成的。生物炭在土壤中的应用通过增加水分和养分的保持能力以及提供有利的微生物栖息地来提高土壤质量。这增加了土壤的有机碳，也减少了土壤中一氧化二氮和甲烷的排放。**在本研究中，将研究缓慢热解过程制备的生物炭在大型生物炭反应堆(工业合作伙伴)中的应用。此外，还将在实验室范围内制备生物炭，以研究其动力学和炭化特性，包括时间-温度历史的影响。由于这些参数在工业规模中是未知的，因此将研究在实验室规模装置中生产的焦炭的形成和质量**。**将调查不同加热速率和其他操作参数对焦炭性能的影响，并将**纳入一个动态数据库中，该数据库将在本项目**完成后继续使用。从生物质热解生产生物炭是一种高效的、**环境可持续的可再生能源。**从运行中的生物炭反应器获得的实验和建模数据将有助于**开发和设计高性能的生物炭反应器。

Biomass is a renewable source of carbon, which can be converted into bio-fuel or other valuable materials.**Pyrolysis is a relatively simple, low-cost thermochemical technology for converting biomass into bio-oil,**biochar and syngas. Biochar is a high carbon content material prepared from heating biomass in an oxygen**deficient atmosphere. Application of biochar in soil increases soil quality by increasing moisture and nutrient**holding capacity and providing a favorable microbial habitat. This increases soil organic carbon, and decreases**emissions of nitrous oxide and methane from soil as well.**In this study, biochar prepared from slow pyrolysis process will be studied for its application in large-scale**biochar reactors (industrial partner). In addition, biochar will be prepared in a laboratory scale in order to study**the kinetics and char properties including effect of time-temperature history. The char formation and the quality**of char produced in lab scale set-up will be studied since these parameters are not known in the industrial scale.**The effect of different heating rates and other operating parameters, on char properties will be investigated and**will be incorporated into a dynamic database, which industrial partner will continue to use following the**completion of this project. The pyrolysis pathway of producing biochar from biomass is an efficient,**environmentally sustainable renewable energy source.**The experimental and modeling data acquired from the operational biochar reactors will be useful in**developing and designing a high-performance biochar reactor.
