项目摘要

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.

生物质是可再生碳的来源，可以将其转化为生物燃料或其他有价值的材料。生物炭是一种高碳含量材料，该材料是由氧气中的加热生物量制备的。生物炭在土壤中的应用通过增加水分和养分**的能力来提高土壤质量，并提供有利的微生物栖息地。这也增加了土壤有机碳，并减少了**从土壤中的一氧化二氮和甲烷的排放。此外，将在实验室规模上制备生物炭，以研究**动力学和魅力的特性，包括时间温度史的影响。由于这些参数在工业规模中未知，因此将研究在实验室规模设置中产生的字符形成和质量**。从生物质中产生生物炭的热解途径是一种有效的，**环境可持续的可再生能源。
