The present work reports on the results from the validation campaign of an autothermal pilot carbonization unit (CarbON) and on the characterization of the produced biochar and pyrolysis vapors. The proposed pilot plant leverages the simplicity and effectiveness of autothermal operations together with open top, downdraft design, to bring to the small scale the performance of larger installations. In autothermal operation, heat for the process is internally provided by combusting part of the feedstock and evolved volatiles inside the reactor, the so called “oxidative pyrolysis”.
