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.
