Production of biochar
Autothermal slow pyrolysis of poplar wood chips in an auger reactor
Short Introductive summary
Growing concerns about greenhouse gas emissions from fossil fuels have prompted the scientific community to develop alternative processes to convert biomass into biofuels and high value-added bio-products. Biomass pyrolysis is globally an endothermic process, and the heat supply is still one of the most important roadblocks to inhibit the scale-up and commercialization of biomass pyrolysis technologies. In this work, oxidative slow pyrolysis of poplar wood chips was investigated in a screw pyrolyzer (SPYRO). Pyrolysis trials were performed at a feed flow rate of 1.5 kg/h, reaction temperature of 500 °C and solid residence time of 30 min, at distinct amount of air injected into the pyrolyzed to study its effect on plant power consumption, as well as on products’ yield and composition. The main aim of the present study was to assess the feasibility of a self-sustained process through oxidative pyrolysis. As a second objective, the study aimed at performing a detailed characterization of the obtained products and the overall mass and energy balances.
